Construction
Electrical Data
Physical Data
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 prior to marking with
indelible ink. The components are then leadformed if required and packed.
