The MMF Series Melf 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. SMD
enabled structure. The resistors are coated
with layers of blue color lacquer.
For resistors operated in ambient temperatures above 70°C, power rating must be derated
in accordance with the curve below.
