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. 3.

The DC or AC (rms) continuous working voltage
corresponding to the rated power is determined by
the following formula:
V =
