PTC (Positive Temperature Coeffi Cient ) PTC is a thermistor with a positive temperature coefficient and a sharp increase in resistance at a certain temperature. thermistor phenomenon or material that can be used specifically as a constant temperature sensor . RT and RT0 indicate the resistance value at temperature T and T0, and Bp is the material constant of the material. The ...

Semiconductor thermistor materials These materials include single crystal semiconductors, polycrystalline semiconductors, glass semiconductors , organic semiconductors, and metal oxides. They all have a very large resistance temperature coefficient and high turtle resistance, and the sensitivity of the sensors made of them is quite high. According to the resistance temperature coefficient can also...
