PTC thermistors are ideal as heating elements because of their specific R/T characteristic. The positive R/T characteristic means that electric power consumed is automatically adapted to the ambient thermal conditions. If the ambient temperature is significantly higher than Tref or heat transfer is restricted, the resistance of the thermistor rises rapidly and power consumption is limited to a very low value. Thanks to these self-regulation properties, heating devices based on PTC thermistors can generally dispense with control and regulating components as well as overtemperature protection.

Special Advantage of our Service:
Centralized purchase of all necessary parts above and equipage them into complete application devices before delivery is greatly helpful for your works as bellow:
-          Completely avoid any quality problem from each separate part because of our inspection procedure (electric items' testing after they were equipage but before delivery).
-          Reduce your packaging costs after the parts are assembled into complete application sets.
-          When the complete application devices were delivered to you, they can reach you by one step. It will avoid any delay because of different delivery time from different parts from different sources.
-          We can also help you to evaluate and choose the most competitive production bases on each part and organize the 3 works above so as to get the most competitive total cost of the application devices.
