Datasheet

3.1 Power rating:

Resistors shall have a power rating based on continuous load operation at an ambient

temperature of 70 к . For temperature in excess of 70 к , The load shall be derate as

shown in figure 1.

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 = ¥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)

In no case shall the rated DC or RMS AC continuous working voltage be greater

than the applicable maximum value.
