PTC thermistors are electronic components whose resistance increases significantly with increasing temperature. They exhibit self-healing properties, rapidly switching to a high-resistance state in the event of overcurrent or overheating, automatically disconnecting the circuit. They also automatically reset themselves after the fault is resolved. They are widely used in circuit protection, motor starting, and temperature sensing.

PTC thermistors are core components for safe, reliable, and long-life preheating and starting in energy-saving lamps and ballasts. Their unique temperature-resistance characteristics enable fully automatic, contactless preheating and control, playing a vital role in improving the overall performance and reliability of lighting products.

PTC thermistors, used for overcurrent and overheat protection, are unique positive temperature coefficient thermistors that play a crucial protective role in modern electronic circuits. Their core function is to utilize their inherent nonlinear resistance-temperature characteristics to rapidly transition from a low-resistance state to a high-resistance state when an abnormal overcurrent or overtemperature occurs in a circuit, automatically shutting off the fault current and protecting subsequent precision components. Once the fault is resolved and the circuit is powered off and cooled, the thermistor automatically returns to its low-resistance state, restoring normal operation without the need for manual replacement.

Motor starting PTC thermistors are automatic starting components designed specifically for single-phase induction motors (such as compressors, refrigerators, and air conditioner motors). Single-phase induction motors cannot generate starting torque on their own and require an auxiliary winding (starting winding) to provide the initial rotating magnetic field. In this starting circuit, the PTC thermistor acts as an "intelligent switch," connecting the starting winding at the moment of startup and automatically disconnecting it once the motor reaches rated speed, ensuring reliable starting and efficient operation.
