Construction

A high purity ceramic substrate is assembled with interference ﬁt end caps to which are welded the terminations. The resistive

element is wound on the substrate and welded to the caps. Flameproof silicone cement coating is applied priorto marking with

indelible ink. The components are then leadformed if required and packed.
