INTrOdUCTION
The FCR Series Carbon Film Flame Proof 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 gray color lacquer.
deraTING CUrVe
For resistors operated in ambient temperatures above 70ºC, power rating must be derated in
accordance with the curve below.
