Film capacitors are widely used in power conditioning, filtering, frequency tuning, and motor control applications. One of the most popular types of film capacitors on the market is the BFC246853684. This capacitor is a unique combination of a metallicized polyester film with a polypropylene dielectric. It is highly praised for its high level of reliability, long service life, low equivalent series resistance (ESR) and low dissipation factor (DF).

The application field of the BFC246853684 includes dc blocking, DC to DC conversion, energy storage, smoothing, and protection. The capacitor is suitable for switching power supplies, motor drive oscillation circuits, inverters, telecommunications, high- power LED lights, and other industrial applications with high reliability requirements and where failure can lead to expensive fines, accidents, or property damage.

The BFC246853684 works in two different manners: as local storage of energy and as a filter or DC blocking element. In the first configuration the capacitor serves as a local capacitor that stores energy and releases it when needed. This helps to reduce the voltage ripple generated by the switching power supply. In the second configuration, the capacitor blocks the DC voltage and passes the AC signal, thus acting as a filter or a blocking element.

In order to understand how the capacitor works, it is important to understand the principle of film capacitors. This type of capacitor is created when two parallel conductors are sandwiched together between two dielectric layers. The dielectric layers are thin insulating materials that separate the conductors and allow the capacitor to store energy. The capacitors also include terminals to provide an electric field which can charge and discharge the stored energy.

The efficiency of the BFC246853684 is determined by its metallized construction. The metallization is done by covering a thin layer of aluminum alloy on the polyester-polypropylene dielectric film. This metal layer improves the mechanical stability of the capacitor and reduces its leakage current. Additionally, the capacitance of the device is determined by the area of overlap of the aluminum alloy layer and the dielectric film.

The BFC246853684 capacitors offer excellent reliability and performance. Their applications include AC & DC blocking, energy storage, current filtering, and DC-DC conversion. Thanks to their robust construction, these capacitors can be used in a variety of operating temperatures, such as -50℃ to +85℃, and can withstand high humidity. This makes them ideal for industrial, automotive, and telecom applications.
