5.1 Derating Curve :
For resistors operated at ambient temperature over 70℃ , power rating shall be derated in
accordance with figure 1.
P Max
Power ratio(%)
5.2 Rated Voltage:
Ambient Temp.(℃)
Figure 1
The rated voltage is calculated by the following formula:
E= P * R
E=Rated Voltage(V)
P=Rated Power(W)
R=Resistance Value(Ω)
E.G. : What is RH10FTN 3003 the rated voltage ?
RH10FTN3003 P=1/8W ; R:3003=300KΩ=300,000Ω
E=√1/8(W)*300000 (Ω) = 193.65 V
Remark : However , it shall not exceed the maximum rated voltage .
