describe
The MF55 is an NTC (negative temperature coefficient) thermistor manufactured using an advanced thin-film process. It represents the future of modern temperature sensing technology and its miniaturization. Compared to traditional block or bead NTC thermistors, it offers significant improvements in performance, reliability, and consistency.
Its core lies in a unique manufacturing process: on an ultra-thin ceramic substrate (such as ceramic), a very thin and uniform metal oxide semiconductor film is deposited as a thermosensitive material through vacuum sputtering or screen printing, and then precise electrodes and circuit patterns are formed through photolithography technology.
In summary, the MF55 thin film thermistor is a high-performance, high-reliability temperature sensing element based on thin film technology. It has the characteristics of high accuracy, response and miniaturization, making it an ideal choice for modern electronic devices with bus requirements for temperature measurement.
Specification
Model: MF55
B value: 3380～4260
Resistance: 5K-500KΩ
Coating: Insulation film coating Working temperature: -40～+125℃
Product features: small size, high precision
Highlight features
1. High stability: The thin film process ensures high consistency and consistency of the temperature sensing material. MF55 generally has a very small resistance tolerance (such as ±1%) and extreme B value consistency, which can provide accurate, stable and repeatable temperature measurement results, and the long-term is therefore very small.
2. Fast thermal response: Because its temperature-sensitive film is very thin and is usually packaged in a fast miniaturized form (such as a chip), its thermal mass is small and its response to temperature changes is extremely fast. The sensing time can be very short, making it very suitable for situations where temperature changes need to be monitored.
3. Miniaturization and High Reliability: The chip or miniaturized package is compact and space-saving, making it very suitable for high-density surface mount (SMT) mounting. The reinforced ceramic structure makes it highly resistant to mechanical vibration and shock, and highly reliable.
4. Wide operating temperature range: It can usually operate in a wider temperature range (for example, -55℃ ~ +125℃ wider), meeting the application requirements of most industrial and consumer electronics.
5. Good linearity: First, for traditional NTC, its resistance-temperature characteristic curve has better linearity within a certain range, and then the subsequent circuit performs signal processing and layout.
Main Applications
It can realize temperature measurement and control: medical electronic equipment (such as thermometers, monitors), laboratory instruments, automotive electronics (such as battery management system BMS, ambient temperature detection).
Temperature compensation: used to compensate for temperature-sensitive components such as crystal oscillators and laser dispersion to ensure their stable working performance.
Consumer electronics: Smartphones, laptops, wearable devices, etc., used to monitor the internal temperature of the device, prevent overheating and achieve intelligent temperature control.
Industry and home appliances: Temperature sensing in industrial automation controllers and smart home appliances (such as coffee machines and air conditioners).
