Description

Insulated Film PTC Heating Element


â–ºThe products PTC thermistor & PTC component are varied. PTC thermistors can be classified as four main groups according to the applications. There are heater series, over-current & over-heating protection series, time delay series and degassing series.


â–ºNotice in appliance. 
1）After switching on, the heating power is large, and then decrease, finally it become steady state. The steady state power changes with appliance conditions. Faster is the heat conduction, higher is the steady state power; higher is the surface temperature, higher is the steady state power.

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

3）Our PTC products are high reliable, long aging, but if they are assembled improperly, the end product may be loose, power or temperature may be unstable. 

4) It operates in long life, and has excellent insulation on high voltage. The surface temperature changes 5~*0℃ only, when supplied voltage changes 2 time. In liquid heating appliance, when liquid was dried in the container, its no problem.

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

Notice:
1) The surface temperature can be selected between *0℃~**0℃, the tolerance of surface temperature is ±7℃ usually. Rate voltage can be 6V~**0V, AC or DC. Customer designed shapes are possible.
2) For getting rapid temperature rising, larger heating power, several PTC pellets are used to assemble into a larger one.
3) All the temperature and rate voltage can be fitted with below dimensions
