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.

Each type rated power at 70 °C:
RC0805=1/8 W; RC1206=1/4 W
RATED VOLTAGE
The DC or AC (rms) continuous working voltage
corresponding to the rated power is determined by
the following formula:
V = √(P X R)
Where
V = Continuous rated DC or AC (rms) working voltage (V)
P = Rated power (W)
R = Resistance value (X)
