Film capacitors are types of capacitors characterized by their use of thin polyethylene films. They have a variety of advantages over conventional capacitors, such as higher capacitance, better stability, higher dielectric insulation strength, better temperature characteristics, and more. They come in many forms, including radial leaded, axial leaded, and surface-mount packages, with the latter being the most commonly used.

BFC247041393 is a type of film capacitor that is used in many applications, such as radios, televisions, and other electronics. Its low ESR (Equivalent Series Resistance) and low reactance makes it ideal for applications that require an extended frequency range and high current. It is also highly temperature and frequency stable, making it suitable for high temperature applications. Here, we will discuss the application field and working principle of this specific type of film capacitor.

Application Field:

BFC247041393 film capacitors are most commonly used in series in filters and matching circuits, DC-DC converters, and voltage-controlled oscillators. They can also be used in noise suppression, output LC filters, lead line filters, input/output EMI filters, and as a buffer circuit element. The wide frequency range and high current capabilities make them well-suited to high-frequency power supplies, audio circuits, and communication equipment.

Working Principle:

Film capacitors work by storing electrical energy in their dielectric layers. This energy is typically transferred between the plates of the film capacitor due to an electrical field or electrostatic force. The plates are typically composed of metal-coated polyethylene terephthalate, or PET, although other materials such as aluminum oxide, polypropylene, and polycarbonate are also used. The dielectric material between the plates determines the amount of energy that can be stored in the device, with higher dielectric constant materials allowing for more energy to be stored.

BFC247041393 is a miniature capacitor that utilizes PET to create an excellent dielectric with low inductance and low voltage coefficient. The capacitance of the device remains stable over both temperature and frequency, making it ideal for applications that require precision operation. Furthermore, its high insulation strength makes it resistant to disruptive discharges.

In summary, BFC247041393 is a miniature film capacitor that is highly temperature- and frequency-stable. It is most often used in series in filters and matching circuits, DC-DC converters, and voltage-controlled oscillators, due to its wide frequency range and high current capabilities. Furthermore, its low ESR and low reactance make it ideal for high-frequency power supplies, audio circuits, and communication equipment.
