PTC THERMISTOR

PTC refers to a positive temperature coefficient thermistor, which is a typical semiconductor resistor with temperature sensitivity, exceeding a certain temperature

At the Curie temperature, its resistance increases in a step wise manner with The increase of temperature

PTC is a positive temperature coefficient thermometer It is a typical semiconductor resistance with temperature sensitivity When the temperature exceeds a certain temperature (Curie temperature), its resistance value increases with

the increase of temperature.
