Construction

A metal film is deposited onto a high dissipation ceramic

former to which tin plated teminating caps are fitted.

The resistor is adjusted to value by a helical cut in the film

and the body is protected by a lacquer coating.

Terminations

Material

Solderability

Marking

Plated steel cap.

The pure tin finish produces ageing free

contacts on which low melting solders can

be used. Dipped area shall be covered with

a smooth and bright solder coating after

3 seconds immersion at 215°C.

Resistance values are colour coded with four bands,

three indicating value and one indicating the multiplier.

(Note this describes standard marking, but certain values

may still be supplied with the addition of a tolerance

band following the multiplier.).

Solvent Resistance

The body protection and marking are resistant to all normal

industrial cleaning solvents suitable for printed circuit boards.
