The FMF Series Metal Film Flame-Proof

Resistors are manufactured using a vacuum

sputtering system to deposit multiple layers of

mixed metal alloys and passivative materials

onto a carefully treated high grade ceramic

substrate. 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 70°C, power rating must be derated

in accordance with the curve below.
