Thermistors are widely used in monitoring temperature in various industrial applications. In this article, we will discuss the application field of the NJ28KA0202F NTC thermistor and its working principle.

Application Field of the NJ28KA0202F NTC Thermistor

The NJ28KA0202F, is a type of NTC thermistor, which stands for negative temperature coefficient thermistor. It has a wide range of applications where temperature control is required within the industrial sector, it is also commonly used in commercial and residential applications. The thermistor has a range of working temperature between -40 °C and 150 °C, and based on the temperatures it is exposed to, it will adjust its electrical resistance.

The NJ28KA0202F thermistor is a popular choice for its high accuracy, repeatability and fast response time at a competitive price point. It is easy to install and has a long life cycle. Generally it’s used for applications such as over-temperature protection, automotive cooling system temperature monitoring, hydrothermal systems and burners. The thermistor can also be used in automatic vending machines, domestic appliances, medical equipment and HVAC controls.

Working Principle of the NJ28KA0202F NTC Thermistor

The NJ28KA0202F thermistor has a two-terminal position and works on the principle of thermodynamics, which states that the heat energy flowing through the thermistor – when exposed to temperature changes – will cause resistance of the electrons to change. By measuring the resistivity of the thermistor, you can accurately tell the temperature of the part it’s monitoring.

A thermistor consists of a ceramic semiconductor which is surrounded by a metal film to provide insulation. When the thermistor is exposed to increases in temperature, the resistance decreases as electrons gain energy and quickly move within the material. The inverse happens when the temperature decreases so the resistance increases as the material cools down.

The sensitivity of the thermistor is determined by the type of material used in the construction of the device, and the NJ28KA0202F thermistor provides an excellent combination of accuracy, reliability and response speed. The material is highly precise and the individual thermistors are tested and calibrated to ensure that there are no discrepancies in readings.

It’s also important to note that thermistors must be connected to a power source when in use – generally a low-voltage DC power source – and will react to temperature to create a voltage drop across the power source. This voltage drop, or temperature-dependent change in voltage, can then be used to create an accurate temperature measurement.

The NJ28KA0202F thermistor is a highly accurate and reliable device that is widely used in a variety of applications. Its easy installation, fast response and long life make it an ideal choice for applications where precise temperature control is paramount.
