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. The unit is then moulded.

Marking

WSM resistors are legend marked with type value and

tolerance.

WSM1 Resistors are marked with value and tolerance.

Solvent Resistance

Flammability

The resistor coating is a flame retardant epoxy to UL 94.
