What are the application scenarios of thermistors in various industries?
Introduction
Thermistors are resistors that are sensitive to temperature changes and are widely used in various electronic devices and systems. Their working principle is based on the characteristic of the material's resistance changing with temperature. They are usually divided into two types: negative temperature coefficient (NTC) and positive temperature coefficient (PTC). NTC thermistors have a decrease in resistance with an increase in temperature, while PTC thermistors have an increase in resistance with an increase in temperature. Thermistors play an important role in modern technology, especially in temperature monitoring and control. This article will explore the application scenarios of thermistors in multiple industries.
