Construction

Termination conductors and ruthenium oxide resistive

material are printed in a non-inductive pattern onto the

surface of a 96% alumina rod to which termination caps

and terminal wires are then attached. The body of the

resistor is then conformally coated either in silicone

(protection code C ) or in epoxy (protection code P) .

Terminations

The termination wires are gold plated.

Marking

Type reference, resistance value and tolerance are

legend marked. The resistance value code conforms to

IE C 62.

Solvent Resistance

The body protection and marking are resistant to all

normal industrial cleaning solvents suitable for printed

circuits.
