ENVIRONMENTAL CHARACTERISTICS
(1) Short Time Over Load Test
At 2.5 times of 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 ± 2.0 %
(2) Voltage Proof on Insulation
The resistor shall be clamped in the trough of a 90° metal V Block. Apply the insulation voltage of 75V
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.

(4) Solderability
Immerse the specimen into the solder pot at 235 ± 5 °C for 3 ± 0.5 seconds.
At least 90% solder coverage on the termination.
(5) Solvent Resistance of Marking
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.
(6) 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 4 kg (40N ).
(7) Damp Heat Steady State
Place the specimen in a test chamber at 40 °C and 93 % relative humidity. Apply the 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 ±2%
(8) Endurance at 70 °C
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
Page-7
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 %.
There shall be no remarkable change in the appearance and the color code shall be legible after the test.
(9) 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。
Temperature Cycling Conditions:

After the test the resistor shall be free from the electrical or mechanical damage.
(10) 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 ± 0.2 %
