Thermistors are temperature-sensitive electronic components that exhibit a significant change in resistance with variations in temperature. They are widely used for temperature sensing and compensation applications in various electronic circuits and systems.
There are two main types of thermistors:
- Negative Temperature Coefficient (NTC) Thermistors: NTC thermistors are the most common type. As the temperature increases, the resistance of an NTC thermistor decreases. This negative temperature coefficient behavior makes NTC thermistors suitable for applications like temperature sensing and control, temperature compensation in electronic devices, and temperature-dependent voltage dividers.
- Positive Temperature Coefficient (PTC) Thermistors: PTC thermistors, on the other hand, exhibit an increase in resistance with rising temperature. They are often used as self-resetting fuses or in applications where temperature-based protection is needed. PTC thermistors can also be employed for temperature sensing, inrush current limiting, and motor protection.
Both types of thermistors offer advantages in specific applications due to their distinct resistance-temperature characteristics. Their small size, fast response time, and sensitivity to temperature changes make them valuable tools in temperature-related circuit designs.
