Film Capacitors

BFC237679622 Application Field and Working Principle

Film Capacitors (also known as Polyester Film Capacitors) are a type of capacitor that uses a very thin polyester film soaked in an electrically conductive material as its dielectric. They are most commonly used in radio frequency (RF) circuits and audio applications, where DC blocking and smoothing of AC signals are required. The construction of Film Capacitors is very simple and efficient, making them a sensible choice in a variety of electronic applications.The BFC237679622 Film Capacitors is a special type of film capacitor featuring high capacitance, high voltage capability, and low dielectric noise. It is ideal for circuits requiring high voltage (from 400V to 4,000V), and frequencies up to 500 kHz. It is suitable for high frequency AC utility applications, motor start-up/running applications, switch mode power supplies etc.

Working Principle

Film Capacitors work by storing and releasing energy through a dielectric, which is the polyester film that is the capacitor’s major component. The film is created from a combination of polyester and an electrically conductive material, such as graphite or aluminum, and is coated in a dielectric material such as epoxy or varnish, and then rolled and sandwiched between two electrodes, which are typically made of brass or aluminum foil.When a voltage is applied across the electrodes, a capacitor is created when the electric field generated by the voltage stored and distributed across the dielectric. This stored energy creates a capacitor action, causing the capacitor to oppose any sudden changes in the voltage or current levels.

Other Applications

Film Capacitors have traditionally been used in radio frequency (RF) circuits and for DC blocking and smoothing of AC signals. However, their high reliability and their ability to handle high voltage have been increasing their application in other areas as well. They are now used in industrial and medical applications, as well as in renewable energy systems. Film Capacitors can also be used in electric and hybrid cars, where their reliability and voltage handling capabilities are essential. In conclusion, Film Capacitors are increasingly being used in a wide variety of applications, thanks to their simple and efficient construction, their strong voltage and frequency capabilities, and their excellent reliability. The BFC237679622 Film Capacitor is an especially reliable and capable kind, and is well-suited for high voltage applications up to 4,000V.
