( If the voltage exceeds the maximum load voltage, the maximum load voltage will be used as the rated voltage ) applied for 5 seconds, the resistor should be free from defects after the resistor is released from load for about 30 minutes Short Time Overload Voltage = 2.5 * Power Rating × Resistance Value The change of the resistance value should be within ± 0.25 % + 0.05Ω (2) Dielectric Withstanding Voltage The resistor is placed on the metal V Block. Apply a Table I dielectric withstanding between the terminals connected together with the block for about 60 seconds. The resistor shall be able to withstand without breakdown or flashover. (3) Temperature Coefficient Test Test of resistors above room temperature 100°C ± 2°C ( Testing Temperature 115°C to 130°C ) at the constant temperature silicon plate for over 5 minutes. Then measure the resistance value. The Temperature Coefficient is calculated by the following equation and its value should be within the range of requested. Re sistor Temperatur e Coefficient = R R0 t to R − R0 1 × × 10 6 R0 t − t0 ＝ Resistance value under the testing temperature ＝ Resistance value at the room temperature ＝ The testing temperature ＝ Room temperature (4) Insulation Resistance Apply test terminal on lead and resistor body.
