BFC246958823

Film Capacitors

The BFC246958823 is a type of Film capacitor that finds its applications chiefly in high frequency AC circuits, such as filtering, decoupling, snubbing and more. It is designed to operate at +85°C to +105°C and has a tolerance range of ±5%.

Film capacitors are also called film-dielectric capacitors, polypropylene capacitors, plastic film capacitors, or simply film caps. They are constructed of two or more metal foils conducting electrodes, each insulated from the other by a plastic film dielectric. They come in many shapes and sizes and serve various purposes within electronic circuits.

Application Field:

The BFC246958823 is an ideal choice for AC filters and snubber circuits. Its capacitance and robustness make it suitable for a wide range of filtering applications. It can be used in high frequency switching power supplies, power factor correction circuits, telecom circuits like PABX\'s, bridges, EMI suppression, variable frequency drive applications and UPS.

In addition, it is also suitable for wireless communication circuits, such as Bluetooth, WiFi, GPS and detection circuits, low EMI circuits, audio-video grids, and many more.

Working Principle:

The working principle of the BFC246958823 depends mainly on the dielectric material used in its construction. The two conducting aluminum foils are insulated from each other by a thin plastic film. This dielectric material is used to store energy and delay the electric current flowing between the two conductors.

The BFC246958823 also comes with an additional conducting layer which serves as a discharge resistor, making it ideal for EMI/RFI suppression applications such as audio-video signals. This feature ensures that the voltage spike is limited, thus protecting any sensitive downstream equipment.

Unlike electrolytic capacitors, the two terminals of the BFC246958823 are symmetrical with a low impedance value, which means that the capacitance remains unaffected even when the frequency changes. This feature also enables the BFC246958823 to perform well in AC circuits.

In conclusion, the BFC246958823 is a highly versatile type of film capacitor that can be used in a variety of applications. Its working principle depends upon the dielectric material used to insulate the two conducting layers, allowing it to store and delay electric current. Its additional features of low impedance values, symmetrical terminals, and its ability to work in high frequency AC circuits make it a viable option for AC filters, snubber circuits, EMI/RFI suppression, and more.
