The MHP Series Metal Film High Precision
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, 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.
