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.

Marking

Resistance values are colour coded with 4 or 5 bands

depending on type.
