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 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. 4.
