High Power Style [ MMP Series ]
INTRODUCTION
The MMP Series Melf Metal Film High Powe
Resistors are manufactured using vacuum
sputtering system to deposit multiple layers
of mixed metals alloy and passivative materi-
als 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 blue color lacquer.
