7. ENVIRONMENTAL CHARACTERISTICS
(1) Short Time Over Load Test
At 2.5 times of the rated voltage or max. overload voltage for 5 seconds, whichever is less; the resistor
should be free from defects after the resistor is released from load for about 30 minutes
Rated Voltage =
Power Rating ´ Resistance Value
The change of the resistance value should be within ± 0.75 % + 0.05Ω
(2) Voltage Proof
The resistor shall be clamped in the trough of a 90° metal V Block. Apply the insulation voltage specified
in the “Table I “ between the terminals connected together with the block for about 60 seconds.
The resistor shall be able to withstand without breakdown or flashover.
Page-5
(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.

(4) Insulation Resistance
Apply "measuring voltage" between protective coating and termination for 1 min.,then measure. The
measuring voltage shall be either 100V±15V d.c. for resistors with an insulation voltage lower than 500V
or 500V±50V d.c. for resistors with an insulatin voltage equal to or greater than 500V.
The test resistance should be high than 1,000M ohm.
(5) Solderability
Immerse the specimen into the solder pot at 245 ± 5 °C for 3 ± 0.5 seconds.
At least 95% solder coverage on the termination.

The specimen into the appropriate solvent of IPA condition of ultrasonic machine for 5± 0.5 minutes.
The specimen is no deterioration of coatings and color code.
(7) Robustness of Terminations
Direct Load – Resistors shall be held by one terminal and the load shall be gradually applied in the
direction of the longitudinal axis of the resistor unit the applied load reached the requirement.
The load shall be held for 10 seconds. The load of weight shall be ≧ 2.5 kg ( 24.5N ).
(8) Damp Heat Steady State
Place the specimen in a test chamber at 40 ± 2 °C and 90 ~ 95 % relative humidity. Apply the 0.1 times
rated voltage to the specimen at the 1.5 hours on and 0.5 hour off cycle. The total length of test is 56
days.
The change of the resistance value shall be within ± 3.0 % + 0.05 Ω

Placed in the constant temperature chamber of 70 ± 3 °C the resistor shall be connected to the lead wire
at the point of 25mm. Length with each terminal, the resistors shall be arranged not much effected
mutually by the temperature of the resistors and the excessive ventilation shall not be performed, for 90
minutes on and 30 minutes off under this condition the rated D.C. voltage is applied continuously for
1000+48/-0 hours then left at no-load for 1hour, measured at this time the resistance value.
The change of the resistance value shall be within ± 3.0 % + 0.05 Ω.
There shall be no remarkable change in the appearance and the color code shall be legible after the test.
Page-6
(10) Temperature Cycling Test
The temperature cycle shown in the following table shall be repeated 5 times consecutively. The
measurement of the resistance value is done before the first cycle and after ending the fifth cycle,
leaving in the room temperature for about 1 hour.

The change of the resistance value shall be within ± 1.0 % + 0.05 Ω
After the test the resistor shall be free from the electrical or mechanical damage.
(11) Resistance to Soldering Heat
The terminal lead shall be dipped into the solder pot at 260 ± 3 °C for 10 ± 1.0 seconds up to 2.5 ~ 3.5
mm.
The change of the resistance value shall be within ± 1.0 % + 0.05 Ω
(12) Pulse Overload
Apply 4 times of rated voltage to the specimen at the 1 second on and 25 seconds off cycle, subjected
to voltage application cycles specified in 10,000 time.
The change of the resistance value shall be within ± 1.0% + 0.05 Ω
