Through-hole resistors General Type Carbon Film Resistors Normal & Miniature Style [ CFR Series ] FEATURES Power Rating 1/6W, 1/4W, 1/2W, 1W, 2W, 3W Resistance Tolerance 2%, 5% T.C.R. see Table 1 DERATING CURVE For resistors operated in ambient temperatures above 70C, power rating must be derated in accordance with the curve below. 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.
