Application of MF52 NTC Thermistors in Smart Home Temperature Monitoring Systems

Product Introduction

MF52 is a bead-type glass-encapsulated NTC thermistor characterized by its miniature size, high sensitivity, fast response, and long-term stability. Its resistance decreases as temperature increases, making it ideal for temperature sensing, control, and compensation in space-constrained environments.

Application Background

Smart home devices such as air conditioners, thermostats, kettles, and air purifiers rely heavily on accurate real-time temperature sensing. MF52 thermistors, with their high sensitivity and fast thermal response, are widely used in these systems for intelligent temperature regulation and over-temperature protection.

Design Recommendations

When using MF52 with MCUs like ESP32 or STM32, it's typically connected via a voltage divider for analog voltage reading. Design tips:

Choose suitable R<sub>25</sub> and B-value based on application range

Add RC filtering before ADC input

Use thermally conductive adhesive for contact sensing

Recommended part: JR0201N103F3380FB for ultra-compact designs

Conclusion

The MF52 thermistor remains a foundational component in modern sensing applications. With compact size and reliable performance, it enables accurate thermal monitoring for smart home, industrial, and medical devices.
