Film Capacitors

Film capacitors are non-polarized, solid capacitors with a dielectric built out of thin plastic film. Their insulation layer can be either a polyester (PET), polypropylene (PP) or polycarbonate (PC) film. Film capacitors are capable of long-term storage of energy and a steady current that is not vulnerable to an electromagnetic pulse. They are thus widely used in power supplies, decoupling, snubbers, etc. The BFC 238056123 is a type of plastic film capacitor, and is well suited for use in audio, power-supply and consumer electronics applications.

Its excellent stability of capacitance and low leakage current make it an ideal choice for decoupling and DC/DC converter applications in power supplies. Its good signal-transmission and filtering characteristics make it an adviseable choice for analog and digital audio application. It could be used in audio circuits, DC-DC converters, switching power supplies, solar panels, protective circuits, and other related applications. Due to its long-term reliability, high-temperature stability, low ESR and low-dielectric absorption, the BFC 238056123 are considered suitable for applications requiring a compact, reliable capacitor.

BFC 238056123 Working Principle

The BFC 238056123 is based on electron-flow theory, thus functioning as a two-electrode capacitor, when voltage is applied across the electrodes, a reversible current flows and the capacitor is charged. An equivalent circuit model is used to explain the working principle for the BFC 238056123. In this model, the equivalent series resistance (ESR) represents the ohmic resistance of the capacitor‘s electrodes and the wires connecting them to the external circuit, the equivalent series inductance (ESL) refers to the inductance of the electrodes and the interference of the connecting wires. The dielectric layer separates two electrodes, and when voltage is applied, an electrical field is created, as electrons move from the positive electrode and occupy the negative electrode, and the dielectric layer creates a leakage path, thus preventing further charging of the capacitor. The BFC 238056123 effectively stores the energy that is generated when voltage is applied, without allowing exposure to electrical interference.

Conclusion

The BFC 238056123 is a type of film capacitor, used in the range of audio, power-supply and consumer electronic applications. It is made up of a non-polarized, solid, plastic film with excellent stability, low leakage current, good signal-transmission property, and filtering characteristics. Its superior dielectric properties make it ideal for DC/DC converter applications in power supplies, and its extended life-cycle makes it suitable for various consumer electronics. The working principle of the capacitor lies in the principle of electron-flow, and the capactior is charged when voltage is applied across the electrodes.
