At 2.5 times of the rated voltage. ( 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 =
The change of the resistance value should be within ± 0.25 % + 0.05Ω (for normal size )
The change of the resistance value should be within ± 0.50 % + 0.05Ω ( for miniature size )
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.
