POWER SOLUTION - NIKKOHM
1W to 14W AXIAL LEAD WIRE WOUND RESISTORS
ARW
Features and Applications
Precision wire wound fixed resistor from 0.5W to 10W rating power.
Operating temperature range from –55C to 275C are performed by using strong silicone
resin.
Welding structure and high purity ceramic core assures long life stability.
Strong over load characteristics are fit for applications of industrial power electronics,
industrial measurements, automatic testing, switching power supplies, motor control
electronics, rush current protection in automotive electronics, industrial power supplies.

+/-50ppm/C and 10ohms and above: +/-20ppm/C.
(2) Rated Power.
Rated power shall be applied under conditions in
which the ambient temperature is in 25C. (Refer
to right figure)
(3) Rated Voltage
Rated voltage shall be obtained from the following
equation E
2
= P*R, where, E is rating voltage, P is
rating power and R is nominal resistance.
