Basic Characteristics
Zero-power Resistance: R
B-Constant: R=R0 expB (1/T1/T0) (1) R: Resistance in ambient temperature T (K), R0: Resistance in ambient temperature T0 (K), B: B-Constant of Thermistor. B= n (R/R0) / (1/T1/T0)
Thermal Dissipation Constant: P=C (T2T1), C: Thermal dissipation constant (mW/C). Thermal dissipation constant is varied with dimensions, measurement conditions, etc.
Thermal Time Constant: Period in which the thermistor's temperature will change 63.2% of its temperature difference from ambient temperature.
Performance Item:
- Resistance: Measured by zero-power in specified ambient temperature.
- Maximum Operating Current: It is possible to keep the thermistor's temperature rising max. 0.1C.
- Thermal Dissipation Constant: Shows necessary electric power that Thermistor's temperature rises 1C by self-heating. It is calculated by the next formula (mW/C). P C = TT0
- B-Constant: Calculated between two specified ambient temperatures by the next formula. T and T0 is absolute temperature (K). n (R/R0) B = 1/T1/T0
