Understanding NTC Thermistors

**NTC thermistors**, or Negative Temperature Coefficient thermistors, are temperature-sensitive resistors that exhibit a decrease in resistance as temperature increases. This unique property makes them invaluable for various applications, particularly in temperature sensing and control. Unlike other types of resistors, NTC thermistors can react quickly to changes in temperature, providing accurate real-time data that is crucial for many electronic circuits.

How NTC Thermistors Work

The operation of an NTC thermistor is based on the semiconductor properties of its materials. When the temperature rises, the increased thermal energy allows more charge carriers to flow, effectively lowering the resistance. This characteristic allows devices to utilize NTC thermistors for **temperature compensation**, **overcurrent protection**, and **temperature monitoring**.
