PTC Heating elementis a kind of new surface-insulated . It is called all-purpose PTC heater by fixing two metal electodes with two leads on both side of general PTC element. Metal electrode having assemblied a pair of belt fuse in two flanks side of average PTC component, Yellow insulative film,Structure are still simple in the metal electrode outward appearance on envelop. The simple-structure heater gives out constant-temperature heat and does not need any additional temperature applications. The high insulation-intension heater has many advantageas follow: 1. simple structure heater gives out constant-temperature heat and not need any additional temperature applications. 2. safety 3. give out heat continuously and keep stady power 4. Itisused in a large range of voltage 5. longer service time 6. Higher reliability 7. dimension is nimble various, may need according to customer reality book make various type specifications. ThePTC Heating element isused for hair permanent clamp ,hair curler,face sauna,heat preservation plate,electric mosquito killer,physical therapy apparatus,hot melt glue gun Product model name of the productlengthwidththicknesstemperaturevoltagethe length of the cableptc heating element70mm13mm3.1mm275 Centidegree220V/110V150mm(length as per your request)PTC Heater element70mm12mm3.1mm255 Centidegree220V/110V155mm(length as per your needed)PTC Heating element64mm12mm2.9mm230 Centidegree220V/110V250MM(length as per your interested in)electric Heating element52mm12mm3.1mm180 Centidegree220V/110V150mm(length as per your request)PTC Heating element35mm10mm2.8mm220 Centidegree220V/110V55mm( as per your interested in )PTC Heating element24mm8mm3.1mm160 Centidegree220V/110V120mm( length as per your needed)PTC heating element24mm6mm2.6mm150 Centidegree 220V/110V125mm(length as per your request) Above information all could customized the orders as per your specifications.
