MF52A202J3470 - Temperature Sensors - NTC Thermistors

NTC thermistors are one type of temperature sensor most commonly used in a variety of applications because of their relatively low cost, small size, and excellent accuracy and stability compared to other temperature sensing technologies. The MF52A202J3470 NTC thermistor is a popular choice for a number of applications, and it is important to have a basic understanding of its working principle and application field to ensure proper use and maximize its potential benefits.

What Is an NTC Thermistor?

An NTC thermistor is a type of temperature sensor that measures the resistance of an electrically-conductive material when warmed or cooled. An NTC thermistor is composed of a small, solid piece of material made of a sintered mixture of metal oxides, such as nickel, cobalt, and manganese. This material is generally encased in a metal or plastic housing, and the resistance of the thermistor can be measured using electrical leads.

The resistance of an NTC thermistor decreases with an increase in temperature, making it ideal for temperature sensing and monitoring applications. As the temperature changes, the electrical resistance of the thermistor changes accordingly and is correlated to a specific temperature range. The resistance of an NTC thermistor is also reversible—as the temperature declines, the resistance of the thermistor increases again.

Characteristics of the MF52A202J3470

The MF52A202J3470 is a popular NTC thermistor manufactured by Panasonic. It features a wide operating temperature range from -40°C to 125°C, making it suitable for both low and high temperature applications. The MF52A202J3470 is relatively small and low-cost, and it has excellent accuracy and repeatability for consistent and reliable temperature sensing.

The MF52A202J3470 is composed of a Metal-Glaze element and is encased in a stainless steel housing. It has a nominal resistance of 2.2KΩ at 25°C and a B coefficient of 3470K. The rated power of the thermistor is 2 mW, and it is available in four different lead form options—axial-leaded, both-leaded, and nickel-plated solutions.

Applications and Working Principle of the MF52A202J3470

The MF52A202J3470 is typically used in temperature sensing and monitoring applications to measure the temperature of liquids, gases, and solids. It is most commonly used for precision temperature sensing, temperature control, and over-temperature protection in consumer electronics, home appliances, medical devices, automotive electronics, and industrial equipment.

The working principle of the MF52A202J3470 is based on the thermistor’s property of changing its electrical resistance in response to changes in temperature. The resistance of the thermistor is measured using electrical leads, and the resistance is then correlated to a specific temperature range. With the MF52A202J3470, the temperature can be accurately determined by measuring the resistance of the thermistor at a given temperature.

Conclusion

The MF52A202J3470 is a popular NTC thermistor manufactured by Panasonic. It has a wide operating temperature range and excellent accuracy and repeatability, making it an ideal choice for temperature sensing and monitoring applications. The thermistor works by changing its electrical resistance in response to changes in temperature, and the resistance can be measured using electrical leads to accurately determine the temperature range. With proper use and understanding of its working principle and application field, the MF52A202J3470 can be a reliable and cost-effective temperature sensing solution.
