7. ENVIRONMENTAL CHARACTERISTICS
(1) Fusing characteristics
(2) Short Time OverLoad Test
(3) Dielectric Withstanding Voltage
(4) Temperature Coefficient Test
(5) Insulation Resistance
(6) Solderability
Fusing Voltage =
R<2.0Ω Fusing time within 30 seconds at 25 times of rated power
R>2.2Ω Fusing time within 30 seconds at 16 times of rated power
Fusing residual resistive value at least 100 times rated resistance
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 ± 2.0 % + 0.05Ω
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.
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 4 to 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.
Apply test terminal on lead and resistor body.
The test resistance should be high than 100M ohm.
Immerse the specimen into the solder pot at 260 ± 5 °C for 5 ± 0.5 seconds.
At least 95% solder coverage on the termination.
