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 resis-

tive layer, tinned connecting leads of electrolytic

copper are welded to the end-caps. The resis-

tors 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.
