(11) Temperature Cycling Test
Immerse the specimen into the solder pot at 260 ± 5 ° C for 5 ± 0.5 seconds.
At least 95% solder coverage on the termination.
Apply test terminal on lead and resistor body.
The test resistance should be high than 10,000M ohm.
The specimen into the appropriate solvent of IPA condition of ultrasonic machine for 1 minutes.
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 reacheds 5 pounds
The load shall be held for 10 seconds. The load of weight shall be
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
Place the specimen in a test chamber at 40 ± 2 ° C and 90 ~ 95 % 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 1,000
hours
The change of the resistance value shall be within ± 1.5 % + 0.05
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 ± 1.5 % + 0.05
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 1 hour
Temperature Cycling Conditions:
The change of the resistance value shall be within ± 0.75 % + 0.05
After the test the resistor shall be free from the electrical or mechanical damage.
