Note:
1. Each test shall be done independently. (not in series tests)
2. *1: Measure after 24 hours left at room temperature.
3. *2: Measure after 2 hours left at room temperature.
4. *3: Pre conditions
(1) IR Reflow : 2 times
(2) Initial values shall be measured after 24 hours at room temperature.
5. Shift in series resistance after the above tests shall be less than ±20% or less than ±15kΩ.
In case of resistance to IR reflow, shift in series resistance after the above tests shall be less than
±30% or ±20kΩ.
In case of resistance to high temperature storage(±125℃ for 1000 hours）, shift in series resistance
after the above tests shall be less than ±40% or ±30kΩ.
