Film capacitors are passive components that are used to store energy in an electrical field. These components are mainly constructed from thin, flexible, plastic and/or paper film, therefore they are sometimes referred to as “Film Capacitors”. In the majority of cases, the film is then rolled and wound up in the capacitor structure, which is then filled with an electrolytic solution or solid dielectric, depending on the application. There are several types of Film Capacitors, including, but not limited to: Aluminum Electrolytic, Polymer, Mica, Ceramic, and Film Foil. Each of these types has its own unique characteristics, thus making it suitable for specific applications. The C4AF1BU4470A11K is a high performance Film Foil capacitor specifically designed for use in high frequency applications such as audio, TV and telecommunications. This type of capacitor has good long term stability, low dielectric losses, and low ESL (Equivalent Series Inductance). The main components of the capacitor are the self-supporting polypropylene (PP) foil, alumina ceramic capacitors and the dielectric oxide.The working principle of a Film Foil capacitor is based on the electric field produced by any two conductors separated by a dielectric material. The value of the capacitance, measured in Farads (F) is proportional to the area of the conductors and inversely proportional to the thickness of the dielectric medium (or distance between the two conductors). When a voltage is applied across two conductors separated by a dielectric medium, a charge (Q) starts to accumulate on both electrodes. The amount of charge that can accumulate on the electrodes is dependent on the value of Capacitance (C), as determined by the formula, Charge (Q) = Capacitance (C) x Voltage (V). This phenomenon forms the basis of a Film Foil capacitor’s working principle.Due to its excellent long-term stability, low ESL and high capacitance range, the C4AF1BU4470A11K is an ideal capacitor for use in high frequency applications such as audio, TV and telecommunication. This capacitor is also capable of withstanding high voltage fluctuations, making it suitable for use in various industrial applications. Moreover, its self-supporting structure eliminates the need for adhesive and further reduces component costs.In summary, the C4AF1BU4470A11K is an ideal Film Foil capacitor for use in a variety of high frequency applications. It has excellent long-term stability, low dielectric losses, low ESL and high capacitance range. This component is also capable of withstanding high voltage fluctuations and its self-supporting construction eliminates the need for additional adhesive. Due to these features, the C4AF1BU4470A11K makes an ideal component for use in commercial and industrial applications.
