NTC thermistors, also known as negative temperature coefficients, are thermistors that are used to sense temperature. The PS303J2 is a NTC thermistor that consists of a ceramic frame, filled with metal oxide, which acts as a resistor. When the temperature increases, the resistance of the oxides decreases. This change in resistance is detected by the thermistor, which then generates a signal indicating that the temperature has changed.

The working principle of the PS303J2 is based on the temperature dependent resistance of a metal oxide semiconducting material. When the temperature of the thermistor increases, the resistance of the metal oxide decreases. This change in the resistance is detected by the thermistor. The thermistor then generates an input signal to indicate that the temperature has changed.

The PS303J2 is used in a variety of applications. It is commonly used in industrial control systems, such as heating and cooling systems, to detect changes in temperature. It is also used in medical devices, such as blood glucose monitors, to measure the temperature of the user’s finger or body temperature. Additionally, the PS303J2 is used in temperature sensing applications in the automotive industry.

The PS303J2 has a number of advantages. Firstly, it is highly accurate and reliable. Secondly, it is resistant to mechanical shock, which makes it suitable for use in a variety of applications. Finally, it is relatively small in size, making it easy to install in a variety of environments.

In conclusion, the PS303J2 is a negative temperature coefficient thermistor used to sense temperature. It works by detecting the change in resistance of a metal oxide semiconducting material when the thermistor is exposed to different temperatures. The PS303J2 has a number of advantages, including accuracy, reliability, and its ability to resist mechanical shock. The PS303J2 is used in a variety of applications, ranging from industrial control systems to automotive temperature sensing.
