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

Chip resistor construction
tolerance trims the value. The
resistive layer is covered with a
protective coat. Finally, the eight external terminations (pure Tin) are added. See fig. 2.

FUNCTIONAL DESCRIPTION
POWER RATING
YC124 rated power at 70°C is 1/16 W
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 (X)
