Resistance Range : <1 Ω

Rated Current : The resistor should have a DC continuous working current or AC (rms) continuous

working current at commercial-line frequencyand wave form corresponding to the power rating as

determined formula as following:

POWER DERATING CURVE

The Operating Temperature Range : -55ºC ~ +155ºC

Power rating or current rating is in the case based on continuous full-load at ambient temperature

of 70ºC. For operation at ambient temperature in excess of 70ºC, the load should be derated in

accordance with the curve below.
