PERORMANCE CHARACTERISTICS

Power Derating Curve

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 figure of derating Curve.

Voltage Rating or Current Rating

Resistance Range: >1Ω

Rated Voltage: The resistor shall have a DC continuous working voltage or a RMS AC

continuous working voltage at commercial-line frequency and wave form

corresponding to the power rating, as determined formula as follows:

E = Rated Voltage (V)

P = Power Rating (W)

R = Nominal Resistance (Ω)

E = √P x R
