CONSTRUCTION:

Thick film material is fired onto high grade ceramic rods. Nickel plated steel caps are force fitted to the rods and the terminations

are welded to the caps. The value is obtained by a helical cut in the film and, finally the resistor body is given a high temperature

protective coating.

TERMINATIONS:

Solder-coated copper wire.

MARKING:

Type reference, TCR code, resistance value, and tolerance code are legend marked.

SOLVENT RESISTANCE:

The body protection and marking are resistant to all normal industrial cleaning solvents suitable for printed circuits.
