8. PACKING METHODS
(11) Temperature Cycling Test
(12) Resistance to Soldering Heat
Bandolier for Axial leads
CFN100
CFN200
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 ± 1.0 % + 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 ± 1.0 % + 0.05 Ω
