The difference between NTC thermistor and PTC thermistor

　　The thermistor is an electronic component whose resistance value changes with temperature. In the working temperature range, its resistance value decreases with the increase of temperature/increases with the decrease of temperature for short, NTC thermistor, on the contrary, Its resistance value increases as the temperature increases / decreases as the temperature decreases, abbreviated as PTC thermistor. In this article, we mainly take a detailed look at their differences:

　　1. Different applications

　　NTC thermistors are mainly used in temperature compensation, temperature measurement, flow test, suppression of surge current and other fields. The PTC thermistor is used in temperature compensation, overcurrent protection, overheating protection, automatic heating, motor starting, color TV degaussing and other fields.

　　2. Different functions

　　NTC thermistor is used for temperature measurement, temperature control, temperature compensation, etc. It can also be used for liquid level sensing.

　　In addition to being used as a heating element, the PTC thermistor can also play the role of a "switch", which has three functions of a sensitive element, a heater and a switch, which is called a "thermal switch".
