Parameter Definitions
| Item | Units | Definition |
|---|---|---|
| Zero power resistor R25 | DC resistance value of the thermistor measured at the specified temperature (251). Measurement should be carried out under conditions where the resistance change due to self-heating is negligible relative to the total measurement error. | |
| Resistance tolerance | % | The maximum allowable deviation range of the actual resistance value of the resistor from the nominal value. |
| Thermal dissipation coefficient | mW/C | The power consumed to raise the temperature of the thermistor by 1. Usually the ratio of power consumption change to temperature change in thermistors at a specified temperature. Testing method refers to GB/T 6663.1. |
| Thermal time constant | s | The time required for the temperature of a thermistor to drop to 63.2% of its initial and final temperature difference under zero power conditions. Testing method refers to GB/T 6663.1. |
| Maximum steady-state current Imax | A | The maximum current that can be continuously applied to a thermistor under ambient temperature conditions of 25. |
| Maximum impulse capacitance Cmax | F | The maximum allowable capacitance value of a capacitor connected to a thermistor under load conditions. |
| Material Constant B | K | Represents the material constant of negative temperature coefficient thermistors using the formula: B=T1T2/(T2-T1)ln (R1/R2) or B=2.303[T1T2/(T2-T1)]log (R1/R2), where T1=298.15K(25C), T2 = 323.15K(50C). |
| Working temperature range | The continuous operating temperature range for which the thermistor is designed under zero power state. |
