CONSTRUCTION
The resistors are constructed out of a high-grade ceramic
body. Internal metal electrodes are added at each end and
connected by a resistive layer. The resistive layer is adjusted
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.
