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. SMD enabled structure and high
power in small packages.
For resistors operated in ambient temperatures above 70°C, power rating must be derated
in accordance with the curve below.
