Resistor Basics
Symbols
Resistors- Largest component count in the electronic circuits- Important elements for circuit performance & long term stability- Functions: regulate electrical current, divide voltage, attenuate signals, bias, matching, compensation, energy consumption, determine time constant,.…etc- Key parameters:- Case size: 0402 (0.04’’ x 0.02’’), ie 1005 (1.0 x 0.5 mm)- Resistance value: mR (Mili Ohm) /R /KR /MR (Mega Ohm)- Tolerance: 5%, 1%, 0.5%, 0.1%, 0.05%, 0.01% (J, F, D, B, W, L tolerance, IEC rule)- TCR (ppm/ °C): Temperature Coefficient of Resistor, less is better (stable)- Rated power (Watts): Allowed max. power dissipation under long-term operation
- △R/R: Resistance value change(%) after reliability/life test, less is better- Ohm’s Law: - (1) I = V/R, I current (amperes), V voltage, and R resistance- (2) P = V2/R, P power (watts), V voltage, and R resistance
