PTC heaters are heating devices designed to utilize the constant-temperature heating characteristics of low-voltage PTC thermostatic heaters. In low- and medium-power heating applications, PTC heaters offer advantages unmatched by traditional heating elements, including constant temperature heating, no open flame, high heat conversion efficiency, minimal influence from power supply voltage, and a long lifespan. Their use in electric heating appliances is increasingly favored by R&D engineers.

Overcurrent protection PTC thermistors are protective components that automatically protect against abnormal temperatures and currents, and are commonly known as “resettable fuses” または “10,000-time fuses.” They replace traditional fuses and are widely used for overcurrent and overheat protection in motors, 変圧器, スイッチング電源, electronic circuits, and other applications.
