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.
