Article Summary

Introduction

NTC (Negative Temperature Coefficient) thermistors are temperature-sensitive resistors commonly used in various electronic circuits and devices. This article aims to provide a comprehensive understanding of NTC thermistors and their applications.

Working Principle

NTC thermistors exhibit a decrease in resistance with an increase in temperature. This characteristic is based on the movement of charge carriers within the thermistor material. The temperature-dependent behavior of NTC thermistors makes them ideal for temperature measurement, compensation, and control.

The diagram below illustrates the basic structure of an NTC thermistor:
