Derating Curve Power rating will change based on continuous load at ambient temperature from -55 to 155℃. It is constant between -55 to 70℃, and derate to zero when temperature rise from 70 to 155℃. 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 commercial-line frequency and waveform corresponding to the power rating, as determined from the following formula: Remark: RCWV: Rating Continuous Working Voltage (Volt.) P: power rating (Watt) R: nominal resistance (Ω) In no case, the rated DC or RMS AC continuous working voltage must be greater than the applicable maximum value. The overload voltage is 2.5 times RCWV or Max. Overload voltage whichever is lower. 8.
