What are Thermistors??
Thermistors are an electronic component whose resistance changes with changes in temperature.

Two kinds of Thermistor

Type	PTC Thermistor Positive Temperature Coefficient	NTC Thermistor Negative Temperature Coefficient
Basic Function	It has almost flat resistance-temperature characteristics near room temperature, but the resistance increases logarithmically when the temperature exceeds a certain level (Curie point). Murata was the first company in the world to commercialize it in 1961.	The resistance decreases logarithmically from low temperature to high temperature. Has a relatively accurate resistance deviation over the entire temperature range. Generally speaking, thermistor refer to NTC Thermistor.
