The resistors are constructed on a high grade ceramic body (aluminum oxide). Internal metal electrodes are added at each end and connected by a resistive paste, which is applied to the top surface of the substrate. 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 coating and printed with the resistance value. Finally, the two external end terminations are added.
To guarantee optimum solder ability the outer layer consists of a lead-tin alloy.
