ENVIRONMENTAL CHARACTERISTICS
(1) Short Time Over Load Test
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 =
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 85°C
±
1°C at the constant temperature silicon plate for over 1
hour at an ambient temperature 165°C. Then measure the resistance value.
The Temperature Coefficient is calculated by the following equation and its value should be within the
range of requested.
