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.
