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 embedded into a glass and
covered by a second glass to prevent environment al
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. 4.

FUNCTIONAL DESCRIPTION
OPERATING TEMPERATURE RANGE
Range: –55 °C to +155 °C
POWER RATING
Each type rated power at 70 °C:
RC0603=1/5W; RC0805=1/4W; RC1206=1/ W; RC2512=2W
R
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 )
Where
V = Continuous rated DC or AC (rms) working voltage (V)
P = Rated power (W )
R = Resistance value ( )
