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 RH12FTN 3003 the rated voltage ?
RM12FTN3003 P=1/4W ; R:3003=300KΩ=300,000Ω
E=1/4(W)*300000 (Ω) = 273.86 V
Remark : However , it shall not exceed the maximum rated voltage .

Resistance value is expressed by 3 digits, the first two digits represent the
significant figures of nominal resistance value inΩ, and the third digit
represents exponent for base of 10.
