Working Principle of NTC Thermistors

NTC thermistors are temperature-sensitive resistors that exhibit a decrease in resistance as the temperature increases. They are made from semiconducting materials and are widely used in various industries, including automotive, aerospace, and electronics. NTC thermistors follow the basic principle of semiconductor behavior, where the number of charge carriers increases with temperature, leading to lower resistance.


NTC thermistors find applications in temperature sensing, temperature compensation, and temperature control systems. Some common uses include:

  • Thermostats
  • Temperature sensors
  • Overheating protection in electronic devices
  • Temperature compensation in precision circuits

Advantages of Using NTC Thermistors

Using NTC thermistors in your electronic circuits offers several advantages, such as:

  1. High sensitivity to temperature changes
  2. Compact size
  3. Wide operating temperature range
  4. Reliable and accurate temperature measurement


While NTC thermistors have many benefits, it’s important to consider their limitations, which include:

  • Non-linear response to temperature changes
  • Requires calibration for precise measurements
  • Limited long-term stability


In summary, NTC thermistors with a 47K resistance value are versatile components that play a crucial role in various temperature-related applications. By understanding their working principle, applications, and advantages, you can effectively incorporate them into your designs and systems.
