No, NTC: negative temperature coefficient thermistor, the higher the temperature, the smaller the resistance value. PTC: positive temperature coefficient thermistor, the higher the temperature, the greater the resistance value. Simply speaking, NTC and PTC are both thermistors, which play the role of protecting the circuit in the circuit.
The initial resistance of NTC is large, so the obstruction of current is greater, can effectively block the peak current, when the circuit tends to be stable, the NTC resistance gradually becomes smaller, so as to protect the circuit.
