Metal Film Fixed Resistor Specifications: Type Rated Power Max. Working Voltage Max. Overload Voltage Dielectric Withstanding Voltage Rated Ambient Temp Operating Temp. Range Resistance Tolerance Resistance Range : MCMF : 0.25W at 70°C : 250V : 500V : 500V : 70°C : -55°C to +155°C : ±1% : 10Ω to 1MΩ Power Rating: Resistors shall have a power rating based on continuous full load operation at an ambient temperature of 70°C. For temperature in excess of 70°C, the load shall be derated as shown in the below figure. 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 curresponding to the power rating , as determined from the following formula : RCWV = √P × R Were : RCWV = R ated DC or RMS AC continuous working voltage at commercial-line frequency and waveform (V) P = Power Rating (W) R = Nominal Resistance (Ω) In no case shall the rated DC or RMS AC continuous working voltage be greater than the applicable maximum value.
