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