NTC thermistors, also known as negative temperature coefficient thermistors, are a type of thermal sensor that operate on the principle of decreasing electrical resistance with increasing temperature. They are widely used in various applications, including temperature measurement, voltage regulation, and electrical power control.

An NTC thermistor consists of a small piece of material, typically a metal oxide, with a high initial resistance. When heated, the resistance of the material decreases rapidly, often in a non-linear fashion. This property allows NTC thermistors to be used as temperature sensors, as the change in resistance is directly proportional to the change in temperature.

NTC thermistors are usually made from a mixture of metal oxides, such as manganese, nickel, and copper, which are combined with other materials to enhance their thermal characteristics. They are available in various forms, including small ceramic or plastic packages, and are often used in combination with other components, such as voltage regulators and thermocouples.

The advantages of NTC thermistors include high sensitivity, fast response times, and low power consumption. However, they also have some limitations, such as a non-linear response to temperature changes, and a susceptibility to damage from overloading. NTC thermistors are commonly used in industrial control systems, medical devices, and automotive electronics, among other applications. They are chosen for their ability to provide accurate and reliable temperature measurements over a wide range of temperatures and environments.

NTC thermistors have been in use since the 1950s and have become a widely accepted technology in temperature measurement and control. The development of NTC thermistors has led to significant advancements in temperature measurement and control, and they continue to play a crucial role in many modern technologies.
