How to Order

PWR 220 - 2 F B R040 J E

Model

PWR = Power Resistor

Package

220 = TO220

221 = TO221

Number of Pins

2 = 2

Function

F = Thick Film

Version

A = TO221 Housing, Surface Mount, 30 W (w/Heat Sink)

C = TO220 Housing/TO221 Housing, Through-Hole, 50 W

(w/Heat Sink)

D = TO220 Housing, Surface Mount, 50 W (w/Heat Sink)

Resistor Value for all Tolerances

<100 ohms ..... “R” represents decimal point

(examples: 7R50 = 7.5 ohms; R040 = 0.040 ohms)

≥100 ohms ..... First three digits are significant, fourth digit represents

number of zeros to follow

(examples: 2000 = 200 ohms; 2002 = 20K ohms)

Absolute Tolerance

J = 5 %

G = 2 %

F = 1 %

Packaging

E = Tape & Reel (Available only for Versions A and D)
