Film Capacitors

Film capacitors refer to any type of capacitor whose dielectric is a plastic film. These capacitors are made up of a dielectric film formed by a thin sheet of organic material or of plastic, such as polyester, polystyrene or polycarbonate, which are adopted as dielectric. The two metal plates, one of which is called anode and the other cathode, are located on both sides of the dielectric film. Depending on the type of dielectric the electric pressure that a film capacitor can withstand ranges from a few volts to some thousands volts, however most of them are capacitors with low voltage.

BFC246851225, which is one type of film capacitor, is built on aluminum electrolytic technology, and has a wide range of applications due to its several advantages: an impedance with an excellent temperature coefficient, a high-performance ripple current, a wide application range of temperature (-50-+105℃ operating temperature), long lifetime (over 20,000 hours under 105℃ operating temperature) and low ESR. The main features of BFC246851225 include an operating voltage of 10V-150V and capacitances range from 1μF – 4,700μF.

Furthermore, it provides suitable performance in combinational circuits for communication devices such as ADSL/VDSL. Its ultra low ESR and ultra low impedance solutions make it perfect for industrial control units, UPS systems, OLED displays, camera modules, etc.

Working Principle

The working principle of the BFC246851225 film capacitor is based on the capacitance between two metal conductors, which are separated by a dielectric film. This film dielectric creates space between the plates and allows electric field lines to travel freely between the two electrodes without the need for a vacuum or any other medium. When a voltage is applied to the plates, a certain amount of current is able to flow through it, creating an electric field throughout the dielectric. This electric field creates an attraction between the electrodes, thereby creating a potential difference between them. This potential difference is known as capacitance, which is the key indicator of the device\'s performance.

This capacitor also features an electrolytic metal plate, which is a thin sheet of metal coated with an electrolyte. This metal plate helps to increase the capacitance of the film capacitor by providing an additional dielectric layer between the two metal conductors. The electrolyte helps to reduce the leakage current, thereby improving the overall capacitance of the film capacitor. Finally, the capacitor is mounted with a metal oxide layer which further helps to reduce leakages and improve the electrical stability of the capacitor.

The working principle of the BFC246851225 film capacitor makes it an ideal choice for a variety of applications, due to its low leakage current, excellent temperature coefficient, high-performance ripple current, wide application range of temperature and long lifetime.

Conclusion

The BFC246851225 film capacitor is a very versatile type of capacitor, due to its wide range of advantages. Its low leakage current, excellent temperature coefficient, high-performance ripple current, wide application range of temperature and long lifetime make it suitable for a wide range of applications, including automotive, medical, consumer electronics, power supplies, UPS systems, and more.
