BFC247049103

Film capacitors, which are also known as foil capacitors, are a type of capacitor that uses a plastic film as the dielectric. They are used in various electronic circuits, and are particularly suitable for applications where low leakage, high stability, high insulation resistance and low dissipation factors are required.

The BFC247049103 is a film capacitor (sometimes known as a foil capacitor) designed for AC applications up to 4kHz. It has a maximum working voltage of 500V, and is constructed using polypropylene film and an aluminium foil electrode. It is rated for 50mA RMS at 398V AC.

Application Field of BFC247049103

Film capacitors are popularly used in AC circuits where a low value of capacitance is required. They are particularly suitable for use in RF circuits, where the high levels of power required can swamp out ceramic capacitors due to their low capacitance values - film capacitors have higher capacitance values. The BFC247049103 is well-suited for RF applications such as mobile phones, digital television and wireless networks. It is also suitable for use in audio equipment and television displays.

Working Principle of BFC247049103

Film capacitors work on the same basic principle as other types of capacitors. When voltage is applied to the capacitor, it stores energy in the form of an electric field between the two electrodes. This stored energy is then released in the form of a current when the capacitor is discharged. The BFC247049103 is an AC capacitor, designed to be used in AC circuits where the polarity of the voltage is constantly changing. This type of capacitor is designed to have low leakage, and can withstand high voltages.

The BFC247049103 is constructed using two thin sheets of electrically conductive material known as electrodes, separated by a very thin layer of polypropylene dielectric material. When voltage is applied to the capacitor, an electric field is set-up between the two electrodes, storing energy as an electric charge. When the voltage is removed, the stored energy is then released in the form of a current.
