PTC Heater Element 170C 200C 220C 250C 220V Constant Temperature Heating Thermistor for Hair Iron Hair Straightener
Product Description
The constant temperature heating characteristic of the PTC thermistor for constant temperature heating is determined by the material characteristics. The principle is that when the PTC thermistor is energized, the temperature of the component body rises due to self-heating, the resistance value enters the jump zone, and the current drops rapidly, so the surface temperature of the constant temperature heating PTC thermistor continues to maintain a constant value. This temperature is only related to the Curie temperature of the PTC thermistor and the applied voltage, and has nothing to do with the ambient temperature.
PTC constant temperature heater is a heating device designed by using constant temperature heating PTC thermistor constant temperature heating characteristics. In the occasion of low and medium power heating, PTC heater has the advantages of constant temperature heating, no open flame, high heat conversion rate, minimal influence of power supply voltage, long natural life and other traditional heating elements. Its application in electric heating appliances is becoming more and more popular. Favored by R&D engineers.
Constant temperature: The heating PTC thermistor can be made into a variety of shapes and structures and different specifications, the common ones are wafer shape, rectangle, strip shape, ring and honeycomb porous shape, etc. Combining the above-mentioned PTC heating elements and metal components can form various forms of high-power PTC heaters.

Use Attention
1) The PTC heater has the characteristics of automatic constant temperature and does not require a temperature control system. It is the core element of all PTC heaters.
2) There are four kinds of electrodes for customers to choose: electroless nickel + silver, melt-blown metal aluminum, printed aluminum + silver, printed aluminum.
3) The working voltage is very wide. When the operating voltage changes twice, the change in surface temperature is very small.
4) When multiple PTC heaters are used together, they should be connected in parallel, not in series.
5) This product has no lead wires and insulation layer. If the customer cannot use it, please choose an insulation film type product or a metal shell type product.

According to customer requirements, the temperature can be designed between 60°C and 280*C, and the operating voltage can be designed between 12V and 240V.
Use Attention
1) The heating power increases from large to small after power-on, and finally stabilizes. The stable power is related to the use conditions. For the same PTC heater, the power may be several times different if the use conditions are different. The faster the heat dissipation, the greater the stable power; the higher the surface temperature of the PTC, the higher the power.
2) The surface temperature of the PTC heating element is controlled by the PTC itself, or it can be controlled by disconnecting the circuit, but the surface temperature cannot be controlled by adjusting the voltage.
3) PTC itself is highly reliable and has a long life span. However, if the product is improperly assembled, the power and temperature of the product will be unstable.
4) When multiple PTCs are used together, they should be connected in parallel, not in series.
