Temperature Sensors - PTC Thermistors is a type of sensor used to measure temperature. The content below will be talking about 202PS1J application field and working principle.

202PS1J Field of Application:

202PS1J is a type of positive temperature coefficient (PTC) thermistor that can detect temperature changes and provide a measure of the temperature of a given object or environment. This thermistor is applied on temperature-sensitive components, such as power transistors, IGBT transistors and other electronics components. By using the 202PS1J in these components, it is easier to develop a thermal protection scheme to prevent any potential thermal runaway. The range of temperature range measured by the 202PS1J is from -40°C to +150°C.

202PS1J Working Principle:

The 202PS1J PTC thermistor is based on the PTC (positive temperature coefficient) sensing property of some semiconductor materials, such as semiconducting polymers and perovskite. This thermistor consists of a semiconductor material in which the resistance of the material increases with increasing temperature. When the ambient temperature changes, the resistance of the semiconductor material also changes, resulting in a measureable change in the output voltage.

The 202PS1J has a built-in temperature-sensing diode, which is connected to a measuring circuit. As the temperature changes, the resistance of the semiconductor material also changes, resulting in a change in the output voltage of the diode. This change in voltage is proportional to the change in temperature and is not affected by the secondary parameters such as air moisture and air pressure. This allows the user to accurately measure the temperature of the object or environment without the need for external compensation.

Conclusion

In conclusion, 202PS1J is a type of positive temperature coefficient (PTC) thermistor used to detect temperature changes and provide a measure of the temperature of a given object or environment. It is used on temperature-sensitive components to provide thermal protection. 202PS1J is based on the PTC sensing property of certain semiconductor materials, and it has a built-in temperature-sensing diode that can accurately measure temperature changes. This allows it to be used in a variety of applications to monitor temperature and prevent potential thermal runaway.
