NTC and PTC are both thermistors, what is the difference between them?

 

NTC: Negative temperature coefficient thermistor, the higher the temperature, the smaller the resistance.
PTC: Positive temperature coefficient thermistor, the higher the temperature, the greater the resistance.


Simply put, both NTC and PTC are thermistors, and both play the role of protecting the circuit in the circuit.
The initial resistance of NTC is large, so the blocking effect on the current is greater, and it can effectively block the peak current. When the circuit becomes stable, the NTC resistance gradually becomes smaller, thereby protecting the circuit.


PTC and NTC are just the opposite. In a stable circuit, PTC is equivalent to a wire. When a temporary pulse signal is encountered, the resistance of PTC increases sharply, and the circuit is equivalent to an open circuit; when the pulse signal leaves, the current decreases, and the PTC resistance The value becomes smaller and the circuit returns to normal.


Summary: NTC handles abnormalities and enables the circuit to conduct normally. It is mainly used for temperature compensation, overcurrent protection, overheating protection, automatic heating, motor start, color TV degaussing, etc.; PTC recognizes abnormalities and cuts off the circuit, which is mainly used for temperature compensation , Overcurrent protection, overheating protection, automatic heating, motor start, color TV degaussing, etc.
