Basic Characteristics
Zero-power Resistance: R
B-Constant: R=R0 expB (1/T1/T0)
Thermal Dissipation Constant: P=C (T2T1), where C is the thermal dissipation constant (mW/C).
Thermal Time Constant: The period in which the thermistor's temperature will change 63.2% of its temperature difference from ambient temperature.
Performance Item Details:
- Resistance vs. Temperature: Measured by zero-power in specified ambient temperature.
- Maximum Operating Current: 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. Calculated by the formula P/C.
- B-Constant: Calculated between two specified ambient temperatures by the formula B = ln(R/R0) / (1/T1/T0). T and T0 are absolute temperatures (K).
