Ps.:can be tailored according to clients’ demand
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
