HOTTEMP – PTC Thermistor
Positive Temperature Coefficient (PTC) Thermistor.
A thermistor using an element with positive temperature coefficient (PTC) in which the resistance increases with temperature rise. Manufactured using such material as a semiconductive ceramic that has barium titanate as its major component. Makes it possible to set a temperature where resistance changes suddenly according to material composition, widely used as a temperature sensor and a low-temperature heating device etc. So-called ceramic heaters use PTC thermistors.
