Basic Characteristics
| Performance Item | Condition / Formula |
|---|---|
| Zero-power Resistance of Thermistor | R=R0 expB (1/T1/T0) |
| B-Constant | B= n (R/R0) / (1/T1/T0) |
| Thermal Dissipation Constant | P=C (T2T1) C: Thermal dissipation constant (mW/C) |
| Thermal Time Constant | Period in which the thermistor's temperature will change 63.2% of its temperature difference from ambient temperature |
| Resistance vs. Temperature Characteristics | Measured by zero-power in specified ambient temperature. |
| Maximum Operating Current | It is possible to keep the thermistor's temperature rising max. 0.1C. |
