iNtRodUCtioN
The NCR Series Carbon Film Non-Inductive &
Flame-Proof Resistors are manufactured by
coating a homogeneous film of pure carbon
on high grade ceramic rods. Tinned connecting
leads of electrolytic copper are welded to the
end-caps. The inductance is
<1μH.
The resistors are coated with layers of gray col-
or lacquer for normal size & pink color lacquer
for miniature size.
deRatiNG CURVe
For resistors operated in ambient temperatures above 70°C, power rating must be derated
in accordance with the curve below.
