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