Physical Data

Construction

A high integrity dielectric layer is applied to a

machined stainless-steel substrate. Thick-

film conductor and resistor patterns are

printed and fired, then protected with a high

temperature overglaze. The termination

pads are tinned with solder and optional

terminals or leads are soldered on.
