CONSTRUCTION
The resistors are constructed out of a high-grade ceramic OUTLINES
body. Internal metal electrodes are added at each end and
connected by a resistive layer. The resistive layer is adjusted For dimension see Table 1
to give the approximate required resistance and laser cutting
of this resistive layer that achieves tolerance trims the value.
The resistive layer is covered with a protective coat and
printed with the resistance value. Finally, the two external
terminations (matte tin) are added. See fig. 5.
