Ps.:can be tailored according to clients’ demand

operating currentIn order to make the test more accurate, the running current should be as less as possible. The following formula is suggested:
I=sqrt(0.005δT^2/(B*R))
PS.:1.sqrt is for square root
2. δ is for dissipation constant in mW/℃
3. T is for temperature in Kelvins
4.B is for the index of the thermal sensitivity
5.R is for zero-power resistance in KOHM
6.final current is in mA
