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.3

FUNCTIONAL DESCRIPTION
POWER RATING
YC158/358 rated power at 70 °C is 1/16 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)
or max. working voltage whichever is less
Where
V=Continuous rated DC or
AC (rms) working voltage (V)
P=Rated power (W)
R=Resistance value (X)
