The MMP Series Melf Metal Film High Power
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, SMD enabled structure and
high power in small packages. The resistors are
coated with layers of lacquer.
For resistors operated in ambient temperatures above 70°C, power rating must be derated
in accordance with the curve below.
