In this article, we will explore the topic of NTC thermistors in Spanish (NTC Thermistor en Español). We will discuss what NTC thermistors are, how they work, their applications, and their advantages and disadvantages. Whether you are an engineer, a student, or simply interested in electronics, this article will provide you with a comprehensive understanding of NTC thermistors.

How NTC Thermistors Work

NTC thermistors, also known as Negative Temperature Coefficient thermistors, are temperature-sensitive resistors. They exhibit a decrease in resistance as the temperature increases. This characteristic makes them useful in various electronic applications such as temperature sensing, temperature compensation, and temperature control.

NTC thermistors are typically made of a ceramic material containing metal oxides. The resistance of an NTC thermistor decreases exponentially with temperature. This behavior is determined by the material composition and structure of the thermistor.

To measure temperature using an NTC thermistor, a simple voltage divider circuit is often employed. By measuring the voltage across the thermistor and knowing the characteristics of the specific thermistor, the temperature can be calculated using appropriate formulas or lookup tables.

Applications of NTC Thermistors

NTC thermistors find wide application in various industries and devices. Some common applications include:

  1. Temperature sensing in industrial and consumer electronics.
  2. Thermal management in power amplifiers and CPUs.
  3. Over-temperature protection in batteries and power supplies.
  4. Temperature compensation in precision circuits and sensors.

Their small size, high sensitivity, and low cost make them ideal for these applications. NTC thermistors are also commonly used in HVAC systems, automotive electronics, and medical devices.

Advantages and Disadvantages

NTC thermistors offer several advantages:

  • High sensitivity to small temperature changes.
  • Compact size, allowing integration into small devices.
  • Wide temperature range of operation.
  • Reliable and robust performance.

However, they also have some limitations:

  • Non-linear resistance-temperature relationship, requiring calibration or lookup tables for accurate temperature measurements.
  • Higher self-heating effect compared to other temperature sensors.

Despite these disadvantages, NTC thermistors are widely used due to their cost-effectiveness and versatility.


In conclusion, NTC thermistors are valuable components in the field of electronics and temperature sensing. They offer high sensitivity, compact size, and a wide range of applications. Whether you are designing electronic circuits, working on an HVAC system, or simply interested in learning more about NTC thermistors, this article should have provided you with a comprehensive understanding of the basics. We hope you found this article informative and helpful in your endeavors.
