Temperature Sensors - NTC Thermistors play an important role in the field of temperature measurement. The MF52C1222F3470 is a series of thermistors developed by Sensitron Technology that is suitable for use in various temperature measurement applications. In this article, I will discuss the application field and working principle of the MF52C1222F3470.

General Application

The MF52C1222F3470 is a type of negative temperature coefficient (NTC) thermistor that is well-suited for temperature sensing. In general, NTC thermistors are used to measure or detect temperature in various industries such as electronics, motor vehicle, air conditioning and refrigeration, telecoms, aerospace and so forth. The MF52C1222F3470 specifically, is used in applications requiring flexible mounting and precise temperature measurement, such as oven and cooking equipment, medical and surgical equipment, room temperature monitoring systems, instruments for measuring temperature in laboratories.

Working Principle

NTC thermistors are resistors whose resistance decreases with an increase in temperature. This is an extremely useful feature in temperature sensing applications, as electrical current can be applied to the thermistor, and the resistance measured to infer the temperature. The basic principle is that the resistance of the thermistor decreases as the temperature rises, providing a feedback mechanism to measure temperature.

The MF52C1222F3470 thermistor is a ceramic chip-type thermistor which consists of a metal body, ceramic core and electrical terminals. At room temperature, the thermistor has a nominal resistance of 10kΩ. As the temperature increases, its resistance decreases in proportion to its temperature coefficient alpha (alpha = -3200K). The MF52C1222F3470 also features a low-current self-heating capability that enables quicker response time and better accuracy.

Mounting Methods

The MF52C1222F3470 thermistor also offers a variety of mounting methods to suit various application needs. The standard mounting method is the SMD (surface-mount device) method, where the thermistor can be directly soldered to the circuit board. This method is suitable for applications in which the thermistor is mounted close to the heating element, providing faster and more accurate temperature readings.

The through-hole-mounting method is also available. In this method, the thermistor is mounted onto the circuit board through a hole, allowing the thermistor to be positioned further away from the heating element without sacrificing accuracy. This configuration is suitable for applications where the thermistor needs to be placed away from the heating element, such as temperature monitoring systems.

Conclusion

The MF52C1222F3470 has many features that make it an ideal choice for a wide range of temperature sensing applications. Its low-current self-heating capability and varying mounting methods make it particularly suitable for applications that require fast and accurate temperature measurement. With its 10kΩ nominal resistance, the MF52C1222F3470 is a reliable and effective temperature sensor.
