The thermistor is an electronic component whose resistance value changes with temperature. Within the operating temperature range, its resistance value decreases with increasing temperature/increases with declining temperature. Conversely, its resistance value rises with the rise of temperature / decreases with the decline of temperature, referred to as a PTC thermistor.

1. Different applications

NTC thermistors are mainly used in temperature compensation, temperature measurement, flow testing, suppression of surge current and other fields. PTC thermistors are used in temperature compensation, overcurrent protection, overheating protection, self-controlled heating, motor starting, color TV degaussing and other fields.

2. Different effects

NTC thermistors are used for temperature measurement, temperature control, temperature compensation, etc. It can also be used for liquid level sensing.In addition to being used as a heating element, a PTC thermistor can also function as a "switch". It has three features: a sensitive element, a heater and a switch, and is called a "thermal switch".
