Formulas:
1. Zero-power Resistance of Thermistor: R=R0 expB (1/T-1/T0) ..............(1)
R: Resistance in ambient temperature T (K) (K: absolute temperature)
R0: Resistance in ambient temperature T0 (K)
B: B-Constant of Thermistor as (1) formula
2. B-Constant: B=Rn (R/R0) / (1/T-1/T0) ............(2)
3. Thermal Dissipation Constant: When electric power P (mW) is spent in ambient temperature T1 and thermistor temperature rises T2, the formula is as follows P=C (T2-T1) ..................(3)
