Resistance temperature characteristic of PTC Thermistor shows that logarithm of resistance is proportional to temperature. Some abruptly increase the resistance at the gradient of 15 to 60%/¡É when reaching the abruptresistance change temperature, while others indicate relatively gradual resistance temperature gradient. Resistance rises abruptly from a certain temperature. The abrupt resistance change temperature ranges from 30 to 320¡É. |
1. PTC Thermistor shows a self-heating function when voltage is applied. When operating point exceeds the maximum current point, the current becomes constant and PTC Thermistor itself automatically regulates temperature. This provides PTC Thermistor PTC Thermistor with a wide range of applications as a constant temperature heating element. 2. When operating point is below the maximum current point, PTC Thermistor shows over current limiting function. |
