PTC resistance heating elements are semiconductor functional ceramics with a positive temperature coefficient. Before reaching the transition temperature, the resistance of PTC heating elements decreases as the temperature increases. From the transition temperature to the thermal runaway temperature, the resistance significantly increases with rising temperature.

PTC heating elements: These are semiconductor functional ceramics with a positive temperature coefficient. Before the transition temperature, the resistance decreases as the temperature rises. From the transition temperature to the thermal runaway temperature, the resistance increases significantly with rising temperature. Zhuohui PTC ceramic heating elements offer advantages such as no open flame, safety and reliability, automatic temperature control, no overheating, fast heating speed, compact size, and a wide voltage operating range. Zhuohui PTC heating elements: They are a new type of thermistor material with characteristics such as constant temperature, time delay, current limiting, and thermal sensitivity. PTC ceramic heating elements offer benefits like 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.

Main applications include: thermostats, electric mosquito repellents, hand warmers, hair clips, electric hair clamps, curling irons, electric irons, mosquito traps, insulated lunch boxes, hand warmers, soldering irons, household oil presses, cotton candy machines, soldering irons, hair straighteners, curling wands, and more.

Due to the wide variety of product models, customers are advised to call for consultation first. After confirming the specific requirements for drawings and samples, our company can produce samples according to customer needs. The sample production time varies depending on the product. For standard products, it usually takes within 10 days, while for non-standard products, specific sample details and timelines will be discussed with the customer. Once the samples are completed, our company will provide specification sheets and product prices. New and existing customers are welcome to call for inquiries!
