INTRODUCTION
The RSF Series Metal Oxide Film Flame-Proof
Resistors offer excellent performance in
applications where stability and uniformity of
characteristics are desired. They provide lower
cost alternatives to Carbon Composition
Resistors and General Purpose Metal Films.
Metal Oxides also can replace many low power
General Purpose wirewound applications, saving
both money and time, with shorter delivery
DERATING CURVE
For resistors operated in ambient temperatures above 70°C, power rating must be derated
in accordance with the curve below.
