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
tolerance trims the value. The resistive layer is covered with a protective
coat and printed with the resistance value. Finally, the two external
terminations are added. See fig.1

the rated power is determined by
the following formula:
V=√ (P X R)
Where
V=Continuous rated DC

following formula:
T.C.R= ------------------------- × 106 (ppm/°C)
Where
t1=+25°C or specified room temperature
t2=–55°C or +155°C test temperature
R1=resistance at reference temperature in ohms
