Temperature Sensors - NTC Thermistors are a kind of negative temperature coefficient thermistor used to measure temperature by changing resistance according to the ambient temperature. NTCSMELFXX203JT is a popular type of NTC Thermistor manufactured by Fenghua Electronics Co., Ltd. with rated resistance of 20k Ohms and rated power of 0.02 watt. In this article, we will discuss the application field and working principle of NTCSMELFXX203JT.

Application Field: The application field of NTCSMELFXX203JT is quite wide. Generally speaking, it can be used in most applications that require temperature measurement, such as environmental monitoring devices, HVAC (heating venting and air-conditioning) systems, refrigeration systems, and medical equipment. In addition, it can also be used in power supply systems, as the accuracy of NTC thermistor can provide reliable temperature measurement for power supply. Aside from temperature measurement, it can also be used as a precision fault detection device for surges and other fault detection parameters.

Working Principle: The working principle of NTCSMELFXX203JT is based on the fact that it has a negative temperature coefficient. This means that when the temperature increases, the resistance decreases and if the temperature decreases, the resistance increases. In other words, it works as an inverse function of temperature. Specifically, when the ambient temperature increases, the resistance of the thermistor decreases, and the current flowing through it increases. This increase in current is then used to calculate the temperature of the environment.

In addition, NTCSMELFXX203JT has other features that make it an ideal choice for temperature measurement. First of all, it has a fast response time, which means that it can accurately measure temperature changes when they occur. Secondly, it is reliable and robust, meaning that it can last for a long time and is not easily damaged. Finally, it also has excellent temperature range, allowing it to measure temperatures between -40°C and 85°C.

To sum up, NTCSMELFXX203JT is a popular type of negative temperature coefficient thermistor that can be used in a wide variety of temperature measurement applications. Its working principle is based on the fact that it has a negative temperature coefficient, and its features such as fast response time, reliability and robustness, and wide temperature range make it an ideal choice for temperature measurements.
