BFC247932165 Datasheet/PDFFilm capacitors (commonly known as film and foil capacitors), as a kind of non-polar aluminum electrolytic capacitor, are now widely used in communication, instrumentation, power rectification, lighting and other fields. BFC247932165 is an aluminum foil and polyester film capacitor with good stability, long life, low loss and good self-healing ability. This paper mainly introduces the application field and working principle of this capacitor.
Application Field of BFC247932165 Film Capacitor
The application field of BFC247932165 film capacitor includes: supporting communication, instrumentation and power supply rectification industries, and supporting products such as audio, lighting, electronic components, film capacitive coupling, high-frequency stabilizing factor, TV, and various circuits in military industries.
Designed for multilayer ceramic capacitor (MLCC) shelves, BFC247932165 film capacitors use a high-speed, high-power chemical vapor deposition (CVD) film series of capacitors to provide customers with products designed for a broad array of applications. In power applications, this form of capacitance provides a higher current and safety resistance rating than mlcc, making it ideal for high-power converters. Similarly, the low equivalent serial inductance (ESL) and high energy density of film capacitors enable successful data communication noise attenuation in high-speed designs. Finally, the improved self-healing property of film capacitors further reduces failures in power conversion and high-speed circuits.
Working Principle of BFC247932165 Film Capacitor
The working principle of BFC247932165 film capacitors is that the electric field exists in the medium of the capacitor, and the electric field of a capacitor is very stable. The electric field depends on the applied voltage, and the strength of the electric field increases with the increase of the applied voltage. And the magnitude of the electric field is proportional to the surface area of the medium; when the electric field strength reaches a certain value, the surface will be broken, thus causing a spark.
When the capacitor is not connected with any voltage, two surfaces still have electric charges with opposite polarity. This is like two pieces of magnets with different poles, and the two charges induced on the plate will also be attractive to each other. This attraction can increase capacitor capacity, so the capacitance of the capacitor will increase. The capacitance of the capacitor can increase this charge. In other words, the electric field increases with the increase of the applied voltage.
BFC247932165 film capacitors have a very stable electrical field. As its electric field is determined by its geometry, the electric field remains unchanged over time and space, preventing distortion or turnover due to changes in voltage or current. On the other hand, the electric field of aluminum electrolytic capacitors depends on the dielectric. The polarization depending on temperature and humidity makes the electric field unstable.
Conclusion
In summary, this paper mainly introduces the application field and working principle of BFC247932165 film capacitors, and explains that BFC247932165 film capacitors have many advantages compared with aluminum electrolytic capacitor, such as good stability, long life, low loss and excellent self-healing ability. Therefore, BFC247932165 film capacitors are widely used in communication, instrumentation and power rectification industries.
