    operating current:

    In 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
