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 commercialline frequency and waveform corresponding to the

power rating , as determined from the following formula :

RCWV = √P x R

Note : Max. Working Voltage or √P x R whichever is lesser

Max. Overload Voltage or 2.5 √P x R whichever is lesser

Where : RCWV = Rated DC or RMS AC continuous working voltage at commercial-line frequency and waveform (volt)

P = Power Rating (watt)

R = Nominal Resistance (ohm)

Nominal Resistance

Effective figures of nominal resistance shall be in accordance :

E-24 values – these are preferred and will have standard MOQ

E-96 values – are available on case by case basis and availability and MOQ need to be confirmed with factory first
