CONSTRUCTION

The resistors are constructed on top of an automotive

grade ceramic body. Internal metal electrodes are

added at each end and connected by a resistive glaze.

The resistive glaze is covered by a lead-free glass.

The composition of the glaze is adjusted to give the

approximately required resistance value and laser

trimming of this resistive glaze achieves the value within

tolerance. The whole element is covered by a protective

overcoat. Size 0603 and bigger is marked with the

resistance value on top. Finally, the two external

terminations (Ni / matte tin) are added, as shown in Fig.8.
