CONSTRUCTION
The resistor is constructed on top of a high-grade
ceramic body. Internal metal electrodes are added on
each end to make the contacts to the thick film resistive
element. The composition of the resistive element is a
noble metal imbedded into a glass and covered by a
second glass to prevent environment influences. The
resistor is laser trimmed to the rated resistance value.
The resistor is covered with a protective epoxy coat,
finally the two external terminations (matte tin on Ni-
barrier) are added. See fig. 2.

ATED VOLTAGE
The DC or AC (rms) continuous working voltage
corresponding to the rated power is determined by
the following formula:
V =
√
(P X R )
