Film Capacitors

Film capacitors are generally composed of two types of components: a dielectric film and electrodes. The dielectric film is the main component of the capacitor, providing insulation between the two electrodes. Generally, the film is a special plastic film, such as polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyester films, polyamides, and polypropylene (PP). The dielectric film is CO-extrusion film technology or cast with vacuum process.

The electrodes are usually made of aluminum or zinc. The surface of the electrodes will be treated with a thin layer of metal like Tin foil, or gold plated. This is to improve the contact with the film and to provide corona protection.

BFC233822684 is a film capacitor. It is designed for high voltage and power frequency applications. It has a very compact structure and low profile design, which makes it ideal for high power systems.

Application Field

BFC233822684 film capacitor is mainly used in high voltage power supply systems. It is designed for applications such as voltage stabilization, power factor correction, harmonic filtering, and surge suppression. It is also used in wind and solar energy systems, HVAC, and EV charging systems.

Working Principle

A capacitor is a device that stores and releases electric energy. It consists of two conductive plates that are separated by an insulating material. When the capacitor is placed in an electric field, it develops an electric charge on its plates. This charge is stored energy and is referred to as the capacitance. The capacitance is determined by the size of the plates and the distance between them.

When the plates of a capacitor are connected to a voltage source, the electric field between the plates changes. This change causes current to flow through the capacitor, which is then stored as electric energy. This process is called charging. When the voltage across the capacitor reaches its maximum, the current stops flowing and the capacitor is said to be fully charged. The capacitor then holds this stored energy until the voltage across the capacitor is reduced, causing the current to start flowing again.

The BFC233822684 film capacitor works in the same way. When the voltage is applied to the terminals of the capacitor, electric field is created between the plates, allowing current to flow. The current is stored as electric energy in the electrical field between the plates. When the voltage across the capacitor returns to its original level, the current stops flowing and the capacitor becomes fully charged.

Thus, BFC233822684 film capacitor can store electrical energy and store it for later use. It is a highly efficient, reliable and cost-effective solution for power applications.
