DerATiNg CurVe
For resistors operated in ambient temperatures above 70°C, power rating must be derated
in accordance with the curve below.

The MFR Series Metal Film 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 blue color lacquer.
