Film Capacitors

Film capacitors, including polymer film capacitors and paper film capacitors, are used in a wide range of applications. Film capacitors are a type of capacitor with a thin layer of polymer, paper, or other dielectric materials sandwiched between two metal plates. They have relatively low values and are able to operate at high frequencies and stability. The most common type of film capacitor is the BFC247990098, a general-purpose polymer film capacitor.

Application Field of BFC247990098

The BFC247990098 is typically used in high current and high frequency applications. These applications include: filtering, buffering, and bypassing; audio-frequency applications such as tone controls and equalizers; power supplies; power amplifiers; and energy storage.

Working Principle of BFC247990098

The basic principle of the BFC247990098 polymer film capacitor is simple: the electrical field created when a voltage is applied to the plates creates a force between them that moves the molecules of the polymer layer in one direction (the direction of the voltage). This creates a charge separation and, in turn, a capacitance.

The actual capacitance of the capacitor can be calculated by using the equation C = Q/V, where Q is the charge stored in the capacitor and V is the voltage applied. If a voltage is applied across the plates, a force appears between them and creates a capacitive field in the sandwiching layer. This field can be measured to calculate the capacitance of the capacitor.

The inherent characteristics of film capacitors, such as their high frequency stability and their ability to handle high currents, make them an excellent choice for use in a variety of applications. Their relatively low values also make them a good choice for filtering and bypassing applications, where small-scale capacitors are required.
