Low-temperature positive temperature coefficient (PTC) heating elements offer advantages such as constant temperature, long lifespan, safety, no open flame, energy efficiency, and minimal impact from current and voltage fluctuations. They are widely used in various heating applications both domestically and internationally. PTC ceramic heating elements are functional semiconductor ceramics with a positive temperature coefficient. Below the transition temperature, the resistance decreases as temperature increases. Between the transition temperature and the thermal runaway temperature, the resistance increases significantly with rising temperature. Zhuohui PTC ceramic heating elements are safe and reliable, with no open flame, automatic temperature regulation, no overheating, fast heating, compact size, and a wide operating voltage range.

Low-temperature positive temperature coefficient (PTC) heating elements provide a series of unparalleled advantages over traditional heating elements, including constant temperature heating, long natural lifespan, energy efficiency, no open flame, excellent safety performance, adjustable heating capacity, and minimal influence from power supply voltage fluctuations. As functional semiconductor ceramics with a positive temperature coefficient, PTC heating elements exhibit decreasing resistance with rising temperature before the transition temperature and significantly increasing resistance between the transition temperature and thermal runaway temperature. Zhuohui PTC heating elements can be customized into various shapes and specifications, such as round discs, rectangular sheets (6-35*6-20*1.5-3.5mm), and circular discs (diameter 5-30*thickness 1.5-3.5mm). Electrodes can be designed using silver or aluminum.

Main applications: cotton candy machines, soldering irons, hair straighteners, hair curlers, thermostats, electric mosquito repellents, hand warmers, hair clips, electric hair clamps, electric hair rods, electric irons, mosquito killers, insulated lunch boxes, hand warmers, electric soldering irons, household oil presses, etc.
