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 molded.
FLAMMABILITY
The resistor coating is categorized as flame retardant epoxy under UL-94.
SOLVENT RESISTANCE
The body protection and marking are resistant to all normal industrial cleaning solvents suitable for printed
circuits.
MARKING
WSM resistors are legend marked with type, value and tolerance.
