3.1 Power rating:
Resistors shall have a power rating based on continuous full load operation at an
ambient temperature of 70 к. For temperature in excess of 70 к , the load shall be
derated as shown in the figure 1.
3.2 Voltage rating:
Resistors shall have a rated direct-current (DC) continuous working voltage or an approximate
sine-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 =
Ѕ
P x R
Were : RCWV = Rated DC or RMS AC continuous working voltage at commercial-line frequency and
waveform (volt)
P = Power Rating (watt)
R = Nominal Resistance (ohm)
