Whether you are an electronics enthusiast or a professional, this guide will provide valuable insights into this fascinating component.

What is NTC Thermistor?

An NTC (Negative Temperature Coefficient) thermistor is a type of resistor whose resistance decreases as its temperature increases. The “20k” refers to the nominal resistance value of the thermistor at a specific temperature, typically 25 degrees Celsius. It is widely used in various electronic circuits for temperature sensing, compensation, and control purposes.

Working Principle

The working principle of an NTC thermistor is based on the relationship between temperature and resistance. As the temperature rises, the movement of charge carriers within the thermistor increases, leading to a decrease in resistance. This behavior is due to the properties of the semiconductor materials used in the thermistor’s construction. By measuring the change in resistance, the temperature can be accurately determined.

Applications

NTC thermistors find applications in a wide range of industries and electronic devices. Here are some common examples:

  1. Temperature measurement and control systems
  2. Thermal protection in power supplies
  3. Overheating detection in motors and transformers
  4. Temperature compensation in electronic circuits

Advantages

There are several advantages of using NTC thermistors:

  • High sensitivity to temperature changes
  • Compact size and easy integration into circuit designs
