Introduction

The YQR100R090 is a temperature sensor in the PTC Thermistor family, allowing for the detection of temperatures ranging from 0℃ to 140℃ or more. The temperature responsive properties of the YQR100R090 provide a wide range of applications, such as temperature compensation, temperature detection, temperature control and over temperature protection.

Application fields and Working Principle

The primary function of the YQR100R090 temperature sensor is temperature detection. The YQR100R090 displays a large positive temperature coefficient (PTC), which allows for the self-heating of the PTC along with the temperature change of its environment. This self-heat promotes the transportation of output voltage and current and enables a temperature detection range between 0℃ and 140℃.The YQR100R090 is also widely used for temperature control and over-temperature protection. The PTC thermistor is composed of a semiconductor element, with a large positive temperature coefficient. As the temperature increases, the resistance of the thermistor also increases. This makes it possible for the YQR100R090 to provide effective temperature control and over-temperature protection, by connecting its resilient lead between two terminals.Moreover, the YQR100R090 can also be used for temperature compensation. Since the PTC thermistor displays a high temperature coefficient, its resistance increases with the temperature variations. As a result, by connecting the PTC thermistor between two terminals, the output voltage and current can be temperature compensated.

Conclusion

In conclusion, the YQR100R090 temperature sensor is widely used for temperature detection, temperature control and over-temperature protection, as well as temperature compensation. It has a very wide temperature range, making it an ideal choice for many applications. The YQR100R090 has proven itself to be an effective and reliable temperature sensor in many applications.
