Some appliances.

dryer, air heater, air condition heater, mosquito killer, car's heater, humidifier, de-humidifier, heating-plate, massager, physical therapy machine, hot glue-gun, hair crimper, hair straightener, coffee /milk warmer, water boiler, and so on. If the surface temperature of end product was under 260, PTC is very suitable as a heating element.

 Notice in appliance.

1) The surface temperature of PTC can be controlled by itself, control circuit and protecting circuit may be omitted in most appliances.

2) It can be used for heating liquid, and its no problem when liquid was dried.

3) It can be used for heating air with fan blowing, and its no problem when the fan did not operate..

4) There are four electrodes coating to be selected: neckel+silver,melt-jet aluminum, screen print aluminum, screen print aluminum+silver.

5) Very long life, 10 years or longer is possible.

6) Very high reliable, over temperature was impossible.

7) The surface temperature increases (or decreases) about 8, when supplied voltage increases (or decreases) 2 time.  

8)  There are no wire, insulator, or shell for this type. Customer could select other types manufactured by our company.

9) Parallel connection is necessary for two or more PTC connection.

10) The steady state power may be very different with different applied condition for same PTC. The faster is the heat conduction, the higher is the steady state power.

11) In most situation, up and bottom electrodes was suitable; only in some very special situation, we use couple up electrodes and two sides electrodes. Selection for some specifications with up and bottom electrodes.
