Application&Characteristics:
1．PTC ceramic thermistor is functional in stabilizing,adjusting and controlling temperatures.
Loaded by alternating or direct current, the temperature of PTC soars up with low resistance value. However,when it exceeds curie temperature, the resistance value arises suddenly and the current would drop to a certain value. Thus temperature is stabilized. For PTC thermistor, additional temperature-control devices are not necessary any more.Besides, different curie temperatures are realizable by adjusting the formula of PTC.
2．Inflammable&Reliable
Compared with fuse, PTC components would not turn red nor on fire when heated.When the ambient temperature overpass the limit, its power would drop to equilibrium value so as to avoid burning.
3．Long life length
As oxide ceramics in nautre, PTC neither oxidize upon high temperature as nichrome wire,nor as fragile as infrared lamps.It is kind of components with long life length.
4. Wild Range of Voltage
PTC components could work normally under either low voltage（3～36V）or high voltage(110-360V).
The low voltage PTC component could be applied in all types of low pressure heaters,low temperature compensation appratus,vehicle heaters ect..
The high voltage PTC is suitable for all electric devices such as shoes drying machine, glue gun, electric cooker, electrothermic boots, mosquito repeller, venous transfusion heater,portable plastic sealer,steam comb,steam generator,humidifier,roller,vedio,copier,vending machine,air curtain, hand warmer, tea baker,pipe heater,dryer,bake painting house,liquefier heater,cosmetic steamer, feeder thermosat,electric acupuncture,electric thermos,electric blanket etc.
