Basic Characteristics
Zero-power Resistance of Thermistor: R = R0 exp[B (1/T 1/T0)]
B-Constant: B = ln(R/R0) / (1/T 1/T0)
Thermal Dissipation Constant: P = C (T2 T1), C = P / (T2 T1) (mW/C)
Thermal Time Constant: Period for temperature to change 63.2% of its difference from ambient temperature.
Performance Item:
- Resistance: Measured by zero-power in specified ambient temperature.
- Maximum Operating Current: Keeps thermistor temperature rise max. 0.1C.
- Thermal Dissipation Constant: Electric power needed for thermistor temperature to rise 1C by self-heating.
- B-Constant: Calculated between two specified ambient temperatures. T and T0 are absolute temperatures (K).
