NTC thermistors, also known as negative temperature coefficient thermistors, are temperature sensors that measure temperature by detecting the incremental changes in electrical resistance that occur when the temperature of the component changes. They are made of a ceramic material that has a negative temperature coefficient, meaning that the electrical resistance decreases when the temperature increases. This property enables NTC thermistors to provide accurate temperature readings and make them the ideal choice for various applications.

The P20BA202M is a commercial-grade NTC thermistor designed specifically for temperature sensing applications in industrial and consumer electronics. It is constructed of a metal oxide ceramic material with a negative temperature coefficient. This allows the P20BA202M to accurately and quickly sense temperature changes and provide a reliable temperature reading. It has a relatively short response time and excellent accuracy over a wide temperature range. Its nominal resistance is 200 kilohms at 25°C and it can measure temperatures from -50°C to 150°C, with an accuracy of ±1.0°C. Typical applications for the P20BA202M include HVAC systems, medical devices, automotive sensing, and industrial control systems.

The working principle of NTC thermistors is that as temperature increases, resistance decreases. This is because of the negative temperature coefficient, which means that the resistance decreases as the temperature increases. The P20BA202M thermistor uses this principle to accurately measure the temperature in its application field. It is mounted on the surface to be measured and the temperature sensitive resistor is connected to a resistance measurement circuit. As the temperature changes, the resistance of the thermistor also changes, and this change is detected and measured by the measurement circuit. This measurement is then used to determine the actual temperature of the surface.

The P20BA202M thermistor is a reliable and accurate temperature sensing component, capable of accurately measuring temperatures over a wide range. Its wide operating temperature range, fast response time, and excellent accuracy make it an excellent choice for many temperature sensing applications, especially in industrial and consumer applications.
