5.1. Derating Curve：
For resistors operated at ambient temperature over 70
℃
, power rating shall be
derated in accordance with figure 1.

5.2. Rated Voltage：
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 RM06JTN102 the rated voltage ?
RM06JTN102
E=
P:1/10W
;
R:102 = 1KΩ = 1000Ω
0.1(W) * 1000(Ω)
= 10 (V)
