Working Principle

As mentioned above, film capacitors, are composed of metalized polypropylene plastic film of a specific dielectric constant k. Capacitors are AC-coupling components that store energy in the form of electrostatic fields when a voltage is applied. For the BFC237525243, when an alternating current a/c) is applied, the side of the capacitor connected to the anode +) terminal is charged with electrons while the side connected to the cathode (-) terminal is charged with positive ions. The electrons and ions repel each other, creating an electric field between them which is stored and then released. This reaction occurs constantly, even as the voltage and direction of the electric current changes, and this action is the working principle of the film capacitor.

Application

Film capacitors are widely used to provide decoupling, filtering, energy storage and signal coupling in applications involving direct current (DC) and low-frequency alternating current (AC). Film capacitors can also be effectively used to reduce EMI/RFI noise, since the capacitance value can be easily changed under different loads which reduces the amount of current and voltage spikes that can be generated.The capacitance value and power level of the BFC237525243 make it ideal for use in consumer electronics, such as smartphones, tablets, TVs, laptops, and other portable electronic devices, as well as commercial, industrial, and automotive applications.
