Rated Voltage
1. The rated voltage for resistor can be a DC continuous working voltage or
AC(rms) voltage in commercial line frequency wave form at rated power. It can be expressed as below.
= ×
E : Rated Voltage(V)
P : Rated Power(W)
R : Nominal Resistance(Ω)
If the value calculated by the equation exceeds Max working Voltage, the rated voltage is limited
to max working voltage. In other words, the lower value is the rated voltage.
ex) For RC1608 Series [ P=0.1(W), Max working voltage = 50(V) ]
1) The rated voltage, when R=1KΩ
= 0.1 × 1000 = 10
Value is lower than Max working voltage,
therefore
= 10()
2) The rated voltage, when R=100KΩ
= 0.1 × 100000 = 100
Value is higher than Max working voltage,
therefore
= 50()
2. When the rated voltage is applied to the resistor, check the ambient temperature and decrease the
lower according to the power derating curve.
3. If higher voltage than rated voltage, the reliability condition and performance cannot be guaranteed.
* If pulse wave is applied, the maximum pulse power should be below the rated voltage.
