Temperature Sensors - NTC Thermistors
MF52A472J3470 is a type of NTC thermistors (Negative Temperature Coefficient Thermistors) designed for temperature sensing applications. It has a highly stable temperature coefficient of resistance (TCR) of -3~\'-8%/K. It also has a wide operating temperature range of -40~150°C. Furthermore, with its small size (4.7mm×2.2mm×4mm) and light weight (just 0.30g), it is ideal for a variety of remote sensing applications.Application Field
The MF52A472J3470 is widely used in temperature sensing applications. It is suitable for detecting temperature in commercial and industrial HVAC systems, such as fan speed control, temperature maintenance, fan cycling, alarm systems, compressor temperature monitoring, burner control, and other temperature related processes. It can also be found in a range of automotive applications, such as temperature measurement for engine controlling and cooling fan control. It can also be used for general purpose temperature measurement in medical, home appliance, and Consumer Electronics.Working Principle
The MF52A472J3470 uses the resistive-switching phenomena which is a result of the physical changes of a thermistor material. A thermistor material is a semiconductor material that has an intrinsic temperature coefficient (TK) which is an indication of its resistance/ temperature relationship. It basically means that the resistance changes with the temperature of the material and this change can be used to measure temperature. A NTC thermistor has a negative TK, and the resistance decreases as the temperature of the thermistor increases.The MF52A472J3470 consists of a ceramic body with two metal electrodes. When the temperature of the NTC thermistor changes, the resistance of the metal electrodes also changes, otherwise known as a change in the TCR (Temperature Coefficient of Resistance). When current passes through the thermistor, a voltage drop is observed across the metal electrodes which can be measured to get an accurate indication of the temperature.Conclusion
The MF52A472J3470 NTC thermistor is a robust and accurate temperature sensing solution for a variety of applications. It has a wide operating temperature range and a highly stable TCR which makes it ideal for use in temperatures controlling/sensing application such as HVAC, automotive, home appliance and consumer electronics. It’s small size and light weight make it suitable for remote temperature sensing applications. By understanding the working principles of the MF52A472J3470, it is possible to accurately measure temperature in a variety of applications.The specific data is subject to PDF, and the above content is for reference
