Ratings:
1 Power rating:
Resistors shall have a power rating based on continuous full load operation at an
ambient temperature of 70 ℃. For temperature in excess of 70 ℃ , the load shall be
derated as shown in the figure 1.
2 Voltage rating:
Resistors shall have a rated direct-current (DC) continuous working voltage or
an approximatesine-wave root-mean-square (RMS) alternating-current (AC) continuous working
voltage at commercial-line frequency and waveform curresponding to the power rating ,
as determined from the following formula :
RCWV = √P x R
Were : RCWV = Rated DC or RMS AC continuous working voltage at commercial-line frequency and
waveform (volt)
