MURATA entered the suppression filter field at an early

stage in response to serious problems stemming from

electromagnetic interference between electronic

equipment. These pioneering efforts in the filter field

resulted in the development and world-wide marketing

of the EMI Suppression Filter (EMIFIL®) which is

produced by combining MURATA's unique ceramic

dielectric technology with its ferrite technology.

The EMI suppression filter for AC power supply

includes for various product types, a common mode

choke coil, and hybrid choke coil MURATA's full range

of high-performance EMIFIL® serve to overcome and

control all types of electronic-equipment noise

problems.

Further, MURATA's various noise suppression circuits,

designed for the diversified needs of the electronic

industry, offer great advantages in the pursuit of noise-

free equipment, etc.

Currently, MURATA is completing a system for the

analysis and solution of noise problems. For the finest

Outline of EMI Suppression Filter (EMIFIL®) for AC Power Lines

1EMI (Electro Magnetic Interference) suppression filter for

AC power lines eliminate noise entering equipment from

commercial power lines or noise generated from electronic

equipment.

Common mode chokes, line bypass capacitors, across the

line capacitors are generally used as AC EMI suppression

filter device. In suppressing common mode noise, common

mode chokes are most important devices. Because the

characteristics of common mode chokes influences

performance of total filter block MURATA provides two types

of common mode chokes. (Standard type, High-frequency

type)

Hybrid choke coil is high performance EMI suppression

device which can suppress both common mode noise and

differential mode noise at the same time. It is effective in AC

power supplies with active device for higher harmonic

countermeasure, which tend to emit relatively higher

differential mode noise.

PLY10 is compact and high performance hybrid choke coilwhich can suppress differential mode noise as well as commonmode noise. PLY10 can solve noise problem in small space,compared to the conventional type by a combination of acommon mode choke coil with a differential mode choke coil.PLY10 does not need to be added differential mode choke coil.

!FEATURES1. PLY10 has both function of common mode choke coil

and differential mode choke coil in its compact body.

2. Because PLY10 does not need defferential mode chokecoil, the temperature rising of circuit can be suppressed.

3. Low Profile even in vertical core layout.

4. PLY10 has same pin layout as conventional typecommon mode choke coils which makes it possible toreplace them.

!APPLICATIONS¡Lighting systems with inverter circuit, CRT displays,

personal computers, facsimiles, color TVs, AC adapters,switching power supplies, etc.

CAUTION

NOTICE

1. Rated Current

Operating Current should not exceed the rated value.

Even if operating current is under the rated value,

adequate ventilation is required to avoid excessive heat

generated within the product (choke coil) and from

surrounding heat sources.

If exceeding these conditions, excessive heat may cause

fumes or permanent damage to the product.

Please ensure that the product (choke coil) is evaluted and

confirmed against the specification when it is mounted in

your final assembled product. Winding temperature should

be less than 120˚C.

*As for FKOB series winding temperature should be less

than 95˚C.

Maximum allowable temperature at the surface of coil

(ambient temperatureWwinding temperature rise) is in

accordance with each safety standard that final assembled

product in applicable to.

When the temperature at winding exceeds maximum

allowable temperature of safety standard, the rated current

should be derated.

2. Inrush Current

Inrush current should not exceed 10 times rated current

within 1/4 cycle of 50/60Hz commercial power line. Inrush

current should be limited to a minimum of 10 seconds after

last inrush.

If these conditions are exceeded, excessive heat may

cause fumes or permanent damage to the component, or

at worst cause ignition.

1. Magnetic Flux Leakage

Choke coils generate small amounts of magnetic flux

leakage that may adversely affect equipment operation

according to component arrangement.

Testing should be completed on final assembly to

ensure equipment performance is not effected.

2. Coil Humming Noise

Magnetic flux generated between coil and core or

between the choke coil windings creates repulsive power

between the coil windings. This repulsive power causes

the coil winding to vibrate and create a humming noise.

The amount of hum produced by the coil is proportionate

to the amount of harmonic distortion generated by the

operating current. This does not influence the electrical

performance of the coils, but it should be considered and

tested in actual circuit application.

3. Soldering conditions

q Flux, Solder

#Rosin-based flux should be used.

Do not use strong acidic flux with halide content

exceeding 0.2wt% (chlorine conversion value.)

#Use 63/37 solder (Sn 63%/Pb 37%) or 60/40 solder

(Sn 60%/Pb 40%).

w Flow Soldering

#Products should be soldered by flow method under

the following conditions.

4. Cleaning

Avoid cleaning product due to non-waterproof

construction.

5. Storage and Handling Requirement

(1) Storage Period

Product should be used within 12 months after

receiving.

Solderability should be checked if this period is

exceeded.

(2) Storage conditions

Storage temperature : Y10 to W40˚C

Relative humidity : 30 to 70%

Avoid sudden changes in temperature and humidity.

Don't keep products in corrosive gases such as

sulfur, chlorine gas or acid, or it may cause

oxidization of lead terminals resulting in poor

solderability or corrosion of component windings.

(3) Handling conditions

Care should be taken when transporting or handling

product to avoid excessive vibration or mechanical

shock.
