Temperature Sensors - NTC Thermistors are widely used in various industrial areas due to their excellent performance in measuring temperatures. The NTC0805J3K0 is a highly accurate thermistor that is suitable for use in such areas. This article will discuss the application field and working principle of the NTC0805J3K0.

Application Field

The NTC0805J3K0 is a small-size thermistor designed primarily for use in temperature sensing and temperature control applications. The thermistor is suitable for various types of environmental monitoring and process control systems, including medical, industrial, automotive, and consumer products. It is also capable of providing reliable temperature measurements in harsh environments due to its robust construction and high accuracy.

The NTC0805J3K0 is most often used in automotive applications, such as temperature sensor modules, exhaust temperature sensors, and intake air temperature sensors. It is also suitable for applications that require temperature measurements in the range of -40 to +150°C, such as in process control and cooling systems, HVAC and refrigeration systems, and medical systems. The thermistor is also suitable for applications involving the monitoring of exhaust gases, engine temperatures, and other high-temperature applications.

Working Principle

The NTC0805J3K0 utilizes the principle of the negative temperature coefficient (NTC) to measure temperatures. This thermistor has a built-in resistive element that can detect a change in temperature from the environment and convert it into an electrical signal. As the temperature increases, the resistance of the NTC thermistor decreases, while as the temperature decreases, its resistance increases.

The thermistor\'s temperature sensing range begins at -40°C and can measure up to +150°C with a high degree of accuracy. Its operating current range is from 0.1mA to 200 mA. The NTC0805J3K0 also features a low power dissipation and a high insulation resistance between the thermistor and the body, which makes it suitable for use in power-sensitive applications, such as portable electronic devices.

The NTC0805J3K0 thermistor also has high stability and long life, making it suitable for use in long-term temperature monitoring applications. It has a low self-heating coefficient, which means that the thermistor is less likely to be affected by adjacent heat sources. It also features a high resistance to thermal shock, meaning that it is reliable in dynamically changing temperatures.

Conclusion

The NTC0805J3K0 thermistor is an ideal choice for a variety of temperature sensing and temperature control applications. It offers excellent performance, high accuracy, and a wide temperature range, making it suitable for use in various industrial areas. By utilizing the theory of the negative temperature coefficient, the NTC0805J3K0 is able to accurately measure temperatures and convert them into electrical signals.
