DESCRIPTION

The resistors are constructed in a high grade ceramic body (aluminum oxide). Internal metal electrodes are

added at each end and connected by a resistive paste that is applied to the top surface of the substrate. The

extra protective metal film is added onto top side electrodes to protect termination from sulfuration. The

composition of the paste is adjusted to give the approximate resistance required and the value is trimmed to

within tolerance by laser cutting of this resistive layer.

The resistive layer is covered with a protective coat. Finally, the two external end terminations are added. For

ease of soldering the outer layer of these end terminations is a Tin (lead free) alloy.
