INTRODUCTION
The MFP Series Metal Film Precision 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, tinned connecting leads of electrolytic copper are welded to the end-caps. The resistors are coated with layers of blue color lacquer. Ultra high precision resistors, ultra high stability, ultra low temperature coefficient.
DERATING CURVE
For resistors operated in ambient temperatures above 70°C, power rating must be derated in accordance with the curve below.
