Filter Design Information

EMI Filter CircuitsThe following is a brief description of the most popular types of EMI Filter circuits and their application.It should be pointed out that these are only general guidelines due to the fact that most impedance conditions and EMI profiles are dynamic, complex, and change with frequency.

• C Circuit Feedthrough Capacitor, 1st Order: A single element shunt feedthrough capacitor has attenuation characteris-tics that increases at a rate of 20 dB per decade. A feedthrough capacitor filter is usually the best choice for filtering lines that exhibit very high source and load impedances.

• L-Circuit Filter, 2nd Order: A two element network consisting of a series inductive component connected to a shunt feedthrough capacitor. This type of filter network has attenuation characteristics that increases at a rate of 40 dB per decade. An “L” circuit filter is best suited for filtering lines when the source and load impedances exhibit large differences. For most applica-tions this type of network provides the greatest performance when the inductor is facing the lower of the two impedances.

• PI-Circuit Filter, 3rd Order: This is a three element filter consisting of two shunt feedthrough capacitors with a series induc-tive component connected between them. This three element filter has attenuation characteristics that increases at a rate of 60 dB per decade. A “PI” circuit filter is usually the best choice when high levels of attenuation are required and when the source and load impedances are of similar values and relatively high.

• T-Circuit Filter, 3rd Order: This also is a three element filter consisting of two inductive components with a single shunt feedthrough capacitors connected between them. Like the “PI” circuit filter, this device has attenuation characteristics that also increase at a rate of 60 dB per decade. A “T” circuit filter is the best choice when high levels of attenuation are required and when the source and load impedances are of similar values and relatively low.

• Double Circuits, 4th, 5th, 6th Orders: Double circuits consisting of four, five, and six elements are best suited when ex-tremely high levels of attenuation are required. Double “L’s” have a theoretical attenuation of 80 dB per decade, while double “PI’s” and double “T’s” have a theoretical attenuation of 100 dB per decade. The source and load impedance conditions that apply to the single circuit devices apply to the double circuit filters.

Filter Installation GuidesCylindrical Style Working Practices• Observe the recommended torque requirements for the specific thread size; 1/4-28 UNF-2A require 44±4 oz-in. and

5/16-24-UNF-2A require 60±4 oz-in.

• Avoid mechanical stress on the filter body. Pliers or other tools capable of excessive pressure on the case must be avoided in all instances. The pressure is capable of cracking the internal ceramic capacitor and/or the glass seals on the terminals.

• Filters are capable of withstanding temperature extremes but care should be observed to avoid rapid heat up and cool down as this can crack the internal ceramic capacitor.

Pre-heating the filter prior to soldering is recommended whenever possible.

Recommended pre-heat: +120ºC ±5ºC, for 15/20 minutes.

Forced air cool down post soldering is not recommended.

• Soldering techniques:

Use a heat sink between the filter body and the point of soldering whenever possible.

Use a temperature controlled soldering iron with a tip temperature of +325ºC ±25ºC.

Use of an 25-40 watt soldering iron is recommended, the use of a larger wattage iron may cause the high temperature solder used in the inside diameter of the terminal tubelet to reflow defeating the hermetic seal and possibly cause heat related damage the ceramic capacitor (thermal fractures).

Use 60/40 or SN 63 RMA flux core solder.

Solder iron tip to point of contact on the terminal flag should be limited to 5-10 seconds when soldering wire to the termi-nal. Excessive contact may possibly reflow the high temperature solder at the tubelet and damage the hermetic seal.

Use caution when soldering wire to the terminal flag. Assure that the correct wire size is specified for the flag terminal slot. Forcing a size wire through the terminal slot that is larger than the slot may cause undue mechanical stress on the terminal and may crack the glass seal. This may also transmit stress to the ceramic capacitor causing micro-fractures.

Solder-In Style WorkingPractices• Soldering techniques:

Pre-Heat unit to +150ºC prior to installation

Increase soldering temperature at a rate of 2ºC-3ºC / second until solder temperature, 300ºC max., is achieved.

The maximum time at solder temperature is 30 seconds;

If lead length permits a heat sink clip is recommended.

A 15 to 20 watt iron is recommended with an iron tip temperature of 238ºC max. and do not apply heat longer than 30 seconds.

60/40 solder is recommended.

Avoid mechanical stress on the filter leads;

The stress is capable of cracking the glass and damaging the internal discoidal capacitor element.

ApplicationsThe CF 12 filter series provides effective filtering over the frequency range of 1 MHz to 10 GHz, which makes it ideal for RF and microwave applications. Designed to be soldered into a housing or bulkhead, it is ideal for hign impedance circuits where large capacitance values are not practical. The “L” circuit incorporates an internal ferrite bead that provides both inductance and resistance (lossy characteristics) which improves insertion loss.

1 Insertion loss measurements shall be made under full load over the frequency range of 1.0 MHz to 10 MHz. Insertion loss measurements above this frequency range under no load.2 The insertion loss requirements between any two adjacent specified frequencies shall be that of the lower of the two frequencies in order to accommodate resonant dips.* Part numbers were previously specified as “FC 103-MAX” and have been amended to “FA” in lieu of “FC”. FC part numbers were designated for Z5U dielectric material for the

ceramic discoidal element and WEMS does not use this unstable material in any of our catalog filters or any custom filters.

Multi-Circuit EMI Filters

Electromagnetic compatibility (EMC) engineers use the con-cept of “noise” to describe the unwanted signals that degrade the performance of electronic equipment. In avionic applica-tions, both external and internal sources of EMI noise can jam sensitive navigation and tactical equipment, possibly even disrupting control of the aircraft. An aircraft carrier’s massive electronics bay might cause interference that scuttles a take-off or landing. EMI affecting satellite transmissions can cause communication failures on the battleground. For these rea-sons, EMI is considered a serious problem, and numerous technologies and techniques have been developed to insure electromagnetic compatibility (EMC) in data transmission sys-tems—from shipboard to undersea, from avionics to space, from aircraft carriers to micro unmanned aerial vehicles.

Sources of EMI Sources of EMI “noise” can be grouped into three categories: 1) Intrinsic noise that arises from random fluctuations within physical systems, such as thermal and shot noise, 2) Man-made noise from motors, switches, power supplies, digital electronics and radio transmitters, and 3) Noise from natural disturbances such as electro-static discharge (ESD), lightning and sunspots.

IntrinsicIntrinsic noise sources can be very subtle and often go unrec-ognized. All electrical systems are potential sources of intrin-sic noise, including such common devices as portable radios, MP3 players, cell phones and so on. These devices can cause interference simply by being on. This is because electrons within a conducting media or a semiconductor device create current flow when excited by external voltages. When the ex-ternally applied voltage stops, electrons continue to move, ran-domly interacting with other electrons and with the surround-ing material. This random electron motion can create noise in conducting media even without current flow.

Man-madeTo protect avionics systems from man-made noise, intentional radio frequency (RF) emitters like cell phones, Bluetooth ac-cessories, CB radios, remote-controlled toys, and walkie-talk-ies are banned outright on commercial airline flights. Laptops, hand held scanners and game players, while not intentional

emitters, can produce signals in the 1 MHz range that can af-fect performance of avionic equipment. Navigation cabling and other critical wiring runs along the fuselage with passengers sitting just a few feet away. Since the thin sheet of dielectric material that forms the interior of the passenger compart-ment— typically fiberglass—offers no shielding whatsoever; and since commercial passenger jets contain up to 150 miles of electrical wiring that can behave like a giant antenna, it is extremely important for passengers to heed regulations on the use of potentially disruptive electronic equipment.

Obviously, these internal sources of EMI are quite dangerous to aircraft because they are so close to the systems they might affect. But external sources, such as radio and radar trans-mitters on the ground, or radar from a passing military plane, cockpit avionics are susceptible to multiple sources of EMI in-cluding man-made interference from iPhones® and other PEDs can be even more disruptive due to the high power and fre-quency of such equipment. As if the many external and internal sources of EMI were not enough of a concern, the aluminum airframe itself, in certain circumstances, can act as a resonant cavity in the 1 to 10 MHz range. Behaving much like a satellite dish, the airframe can compound the effects of both internal and external EMI by concentrating man made and naturally-occurring transient signals and broadcasting the interference into nearby equipment. A recently released report from a major aircraft manufacturer illustrates the ongoing concern with pas-senger-carried portable electronic devices (PED). The number of these devices on commercial airplanes has mushroomed, particularly with the advents of new classes of laptop devices such as the Apple iPad.

The use of PEDs produces uncontrolled electromagnetic emis-sions that have the potential to interfere with avionic systems. While aircraft avionics gear is tested and qualified to rigorous electromagnetic standards PEDs are not subjected to even a fraction of the same testing and qualification regimens for elec-tromagnetic compatibility. As system speeds have increased, the voltage levels of data signals have necessarily decreased, making them much more susceptible to performance degra-dation by unwanted electronic noise—particularly the com-bined noise of large numbers of PED’s operating within a single aircraft.

Why do you need an EMI Filter?



The frequency bands used by avionic systems span the electromagnetic spectrum from a few kilohertz to several gigahertz. At the low end, Omega Navigation, which is used to fix aircraft position within a network of ground based transmit-ters, operates in the frequency range of 10 to 14 KHz. VHF Omnidirectional Range Finders (VOR) are radio beacons used in point to point navigation. They operate from 108 to 118 MHz. Glideslope Systems used during landings operate in the 328 to 335 MHz range. Distance-Measuring Equipment (DME), which gauges the space between the aircraft and ground-based transponders operate at just over 1 GHz. Also in the spectrum above 1 GHz are global positioning, collision avoidance, and cockpit weather radar systems. Personal Electronic Devices (PEDs) operate at frequencies from 10 to 15 KHz for AM radios and up to 400 MHz for laptop computers. When the higher harmonics of these signals are taken into account, the emitted frequencies cover almost the entire range of navigation and communication frequencies used on the aircraft, and PEDs, are just a single class of EMI emitters. When the full spectrum of other radiated and conducted EMI emitters are taken into account, it becomes clear that the entire system of electronic equipment aboard commercial and military aircraft are at risk to EMI.

Naturally Naturally occurring noise sources such as ESD, lightning or other energy surges also present significant life safety and equipment damage potential. A poorly grounded device can transmit dangerous energy from a transient surge to a tech-nician, user or any other passerby. Sensitive semiconductors and other components can be damaged or destroyed. Solu-tions to naturally occurring noise include:

• Eliminate static buildup at the source • Insulate the device properly • Provide an alternative path for the discharge or surge to

bypass the circuit • Use of EMI Filters with Transient Suppression

In conclusion, it is becoming more and more apparent that EMI/EMC is a growing concern for both the military and com-mercial industries for all forms of electronic equipment. In re-sponse to the increasing demand for low-cost and effective EMI/EMC solutions, WEMS Electronics is here to solve your most challenging requirements and would welcome any op-portunity to demonstrate our expertise on your new & upgrade program requirements.

This random electron motion can create noise in conducting media even without current flow.

Man-madeTo protect avionics systems from man-made noise, intentional radio frequency (RF) emitters like cell phones, Bluetooth ac-cessories, CB radios, remote-controlled toys, and walkie-talk-ies are banned outright on commercial airline flights. Laptops,

hand held scanners and game players, while not intentional emitters, can produce signals in the 1 MHz range that can af-fect performance of avionic equipment. Navigation cabling and other critical wiring runs along the fuselage with passengers sitting just a few feet away. Since the thin sheet of dielectric material that forms the interior of the passenger compart-ment— typically fiberglass—offers no shielding whatsoever; and since commercial passenger jets contain up to 150 miles of electrical wiring that can behave like a giant antenna, it is extremely important for passengers to heed regulations on the use of potentially disruptive electronic equipment.

Obviously, these internal sources of EMI are quite danger-ous to aircraft because they are so close to the systems they might affect. But external sources, such as radio and radar transmitters on the ground, or radar from a passing military plane, cockpit avionics are susceptible to multiple sources of EMI including man-made interference from iPhones® and other PEDs can be even more disruptive due to the high power and frequency of such equipment. As if the many external and in-ternal sources of EMI were not enough of a concern, the alu-minum airframe itself, in certain circumstances, can act as a resonant cavity in the 1 to 10 MHz range. Behaving much like a satellite dish, the airframe can compound the effects of both internal and external EMI by concentrating man made and nat-urally-occurring transient signals and broadcasting the interfer-ence into nearby equipment. A recently released report from a major aircraft manufacturer illustrates the ongoing concern with passenger-carried portable electronic devices (PED). The number of these devices on commercial airplanes has mush-roomed, particularly with the advents of new classes of laptop devices such as the Apple iPad. The use of PEDs produces uncontrolled electromagnetic emissions that have the potential to interfere with avionic systems. While aircraft avionics gear is tested and qualified to rigorous electromagnetic standards PEDs are not subjected to even a fraction of the same testing and qualification regimens for electromagnetic compatibility. As system speeds have increased, the voltage levels of data signals have necessarily decreased, making them much more susceptible to performance degradation by unwanted elec-tronic noise—particularly the combined noise of large numbers of PED’s operating within a single aircraft.

Why do you need an EMI Filter?



The frequency bands used by avionic systems span the electromagnetic spectrum from a few kilohertz to several gigahertz. At the low end, Omega Navigation, which is used to fix aircraft position within a network of ground based transmit-ters, operates in the frequency range of 10 to 14 KHz. VHF Omnidirectional Range Finders (VOR) are radio beacons used in point to point navigation. They operate from 108 to 118 MHz. Glideslope Systems used during landings operate in the 328 to 335 MHz range. Distance-Measuring Equipment (DME), which gauges the space between the aircraft and ground-based transponders operate at just over 1 GHz. Also in the spectrum above 1 GHz are global positioning, collision avoidance, and cockpit weather radar systems. Personal Electronic Devices (PEDs) operate at frequencies from 10 to 15 KHz for AM radios and up to 400 MHz for laptop computers. When the higher harmonics of these signals are taken into account, the emitted frequencies cover almost the entire range of navigation and communication frequencies used on the aircraft, and PEDs, are just a single class of EMI emitters. When the full spectrum of other radiated and conducted EMI emitters are taken into account, it becomes clear that the entire system of electronic equipment aboard commercial and military aircraft are at risk to EMI.

Naturally Naturally occurring noise sources such as ESD, lightning or other energy surges also present significant life safety and equipment damage potential. A poorly grounded device can transmit dangerous energy from a transient surge to a tech-nician, user or any other passerby. Sensitive semiconductors and other components can be damaged or destroyed. Solu-tions to naturally occurring noise include:

• Eliminate static buildup at the source • Insulate the device properly • Provide an alternative path for the discharge or surge to

bypass the circuit • Use of EMI Filters with Transient Suppression

In conclusion, it is becoming more and more apparent that EMI/EMC is a growing concern for both the military and com-mercial industries for all forms of electronic equipment. In re-sponse to the increasing demand for low-cost and effective EMI/EMC solutions, WEMS Electronics is here to solve your most challenging requirements and would welcome any op-portunity to demonstrate our expertise on your new & upgrade program requirements.
