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
approximately required resistance and laser cutting
of this resistive layer that achieves tolerance trims
the value. The resistive layer is covered with a
protective coat and printed with the resistance value.
Finally, the three external terminations (Cu/Ni/matte tin)
are added, as shown in Fig.5.

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 (Ω)
