Thermistors are electronic components in which the resistance changes with the change of temperature.
Thermistors are categorized into the following 2 types according to how the resistance changes.

NTC Thermistors


What is an NTC Thermistor? >

Function Temperature Characteristics Appearance / shape
The resistance drops as the temperature increases.
For temperature sensing, compensation and inrush current suppression.

PTC Thermistors


What is an PTC Thermistor? >

Function Temperature Characterristics Appearance / shape
The resistance remains constant up to a certain temperature, and  suddenly increases at a certain critical temperature.
For overheat sensing, overcurrent protection, inrush current suppression and heater.
