The Working Principle and Characteristics of NTC Thermistor

Temperature measurement and control are key factors affecting the performance and safety of equipment. NTC thermistor are highly reliable and precise temperature-sensitive components, widely used in various industrial, automotive, household, and medical devices. This article will detail the working principle and characteristics of NTC thermistor.

1. Working Principle of NTC Thermistor

The core feature of NTC thermistor is their negative temperature coefficient, meaning that their resistance decreases as the temperature rises. This characteristic is determined by the semiconductor material inside. When the temperature increases, the number of free carriers in the material increases, enhancing conductivity and thus reducing resistance. It is precisely this property that enables NTC thermistor to accurately sense temperature changes and be widely applied in various temperature measurement and control systems.
