DERATING CURVE INTRODUCTION
The CFR Series Carbon Film Resistors are manufactured by coating a homogeneous film of pure carbon on high grade ceramic rods. After a helical groove has been cut in the resistive layer, tinned connecting leads of electrolytic copper are welded to the end-caps. The resistors are coated with layers of tan color lacquer. For resistors operated in ambient temperatures above 70°C, power rating must be derated in accordance with the curve below.
