Notes:

1. To ensure more accurate testing, the operating current should be minimized as much as possible. Suggest the following formula:

I=sqrt (0.005 δ T ^ 2/(B * R)) --- PS.: 1. sqrt is the square root 2. δ

2. Dissipation constant, unit: mW/℃

3. T represents Kelvin temperature

4. B represents the index of thermal sensitivity

5. R represents the zero power resistor in KOHM

6. The final current unit is mA
