Chip PTC heating element


1. Shape structure.


There are 3 types of chip PTC heating element structures, double-sided electrode extraction type, single-sided electrode extraction type, and side electrode extraction type.




2. Examples of uses.


Heater, air conditioner heating, clothes dryer, mosquito killer, motorcycle carburetor, automobile choke door, automobile cold start preheating, electric humidifier, electric instrument moisture-proof heating, electric heating plate (pan), massager, hyperthermia Instrument, glue gun, curling hair, hair straightener heating, hot coffee machine, milk heater, water heater, water heater, steam beauty, etc. When the terminal temperature of the product is below 260℃, PTC heating can maintain constant temperature without temperature control, compact structure, long life, and great advantages.




3. Use caution.


1) The PTC heating element has the characteristics of automatic constant temperature, no temperature control system is needed, and the PTC can be directly energized.


2) When the PTC heating element is used to heat liquid (such as water), the PTC heating element will not be damaged after the liquid is dried.


3) If the PTC heating element is used to heat cold air, the PTC heating element will not be damaged when the air is not supplied.


4) There are four kinds of electrodes for customers to choose: electroless nickel + silver (weldable), melt-blown metal aluminum, printed aluminum + silver, printed silver zinc + silver (weldable), printed aluminum.


5) Long service life, under normal environment, the service life can reach more than 10 years.


6) Reliable work, using the internal characteristics of PTC to control temperature, never over-temperature.


7) The change of working voltage has relatively little influence on the surface temperature. When the working voltage increases 2 times (or drops 1/2), the surface temperature rises (or drops) by about 8°C.


8) This product does not have wires and insulation layers. Customers also choose our company's products with wires and insulation layers, or products with shells.


9) When multiple PTCs are used together, they should be connected in parallel, not in series.


10) Different heat dissipation conditions make the heating power of PTC vary greatly.
