PTC Ceramic Resistor Heating Element: When AC or DC voltage is applied to the PTC heating element, below the Curie point temperature, the resistivity is very low, and the heating rate is very fast. Once the temperature exceeds the Curie point, the resistivity suddenly increases, causing the current to drop to a stable value, achieving automatic temperature control and constant temperature without the need for additional temperature control circuitry. Moreover, the Curie temperature of the PTC element can be adjusted through formulation to meet different temperature requirements. Zhuohui's PTC heating elements can be manufactured in various shapes and specifications as needed. Common shapes include discs, rectangles (square pieces 5-40*width 5-15*thickness 1.8-3.0MM), and circular pieces (diameter 6-26*thickness 1.8-3.0MM). Electrodes can be designed using silver or aluminum. Common product shapes include square, circular,扇形 (fan-shaped), and perforated.

Main application areas: Insulated lunch boxes, hand warmers, electric soldering irons, household oil extractors, 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, and other fields.

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 requirements. The sample production time varies for different products, with常規(guī)品 (standard products) generally taking within 5 days, while非常規(guī)品 (non-standard products) require communication with customers regarding specific details and time. After sample completion, our company will provide specification sheets and product prices. New and existing customers are welcome to call for consultation!
