(10) Resistance to Soldering Heat
The specimen into the appropriate solvent of IPA condition of ultrasonic machine for 1 minute.
The specimen is no deterioration of coatings and color code.
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 2 pounds 。
The load shall be held for 5 seconds. The load of weight shall be ≧ 0.9 kg ( 9N ).
Place the specimen in a test chamber at -10 °C＋ 65 °C and 80 ~ 98 % 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 240
hours. The change of the resistance value shall be within ± 0.5 % + 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 ± 1.0 % + 0.05 Ω.
There shall be no remarkable change in the appearance and the color code shall be legible after the 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 0.5 hour。
Temperature Cycling Conditions:
The change of the resistance value shall be within ± 0.015 % + 0.05 Ω
After the test the resistor shall be free from the electrical or mechanical damage.
The terminal lead shall be dipped into the solder pot at 350 ± 10 °C for 3 ± 0.5 seconds up to 2 ~ 2.5 mm.
The change of the resistance value shall be within ± 0.1 % + 0.05 Ω
