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 paste. The

composition of the paste is adjusted to give the

approximately 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 three external terminations (Cu/Ni/matte tin)

are added, as shown in Fig.5.
