Film capacitors, also known as plastic film capacitors, are components that store electrical energy in the form of an electrostatic field. They contain a thin plastic film coated with metal or dielectric material. Depending on the type of film used, the capacitor will have different properties. The BFC247952824 is a type of film capacitor that has a wide range of application fields and a unique working principle.

Application Fields

The BFC247952824 film capacitor is particularly well suited for use in large, high power equipment and power supplies. Its capacitance can range from 2.2nf to 4.7nf with a tolerance of 10%. This allows it to be used in applications that require a large capacitive load, such as power supplies, motor drives, transformers, and power amplifiers.

The BFC247952824 film capacitor is also suitable for use in applications that need its low equivalent series resistance (ESR). Its ESR ranges from 2mΩ to 4mΩ, meaning that it can dissipate more heat than other film capacitors. This makes it a great choice for power supplies or motors that need to dissipate a lot of energy.

In addition, the BFC247952824 film capacitor is a reliable choice for high frequency applications. Its self-healing properties and high voltage rating make it ideal for use in switching power supplies, digital circuits, and conversion circuits that operate at frequencies from 100kHz to 1MHz.

Working Principle

The working principle of the BFC247952824 film capacitor is quite peculiar. The capacitor consists of two plastic films, each coated with metal or dielectric material. The films are placed very close to each other and an electric field generated between them. When a voltage is applied, the electric field attracts ions from the metal layers and accumulates them at the contact points between the two films. This build-up of ions creates a depletion region that increases the capacitance.

The electric field generated between the films is also responsible for the self-healing property of the BFC247952824 film capacitor. If an electric current passes through the capacitor, it can create hot spots in the film, causing them to expand and eventually break. However, the electric field generated between the films pushes the hot spots back to their original position, effectively repairing the damaged section.

The BFC247952824 film capacitor is designed to have a high voltage rating and a long life. Its high voltage rating makes it suitable for applications in high power circuitry, while its long life makes it a reliable choice for long-term use. It is also designed to be able to withstand extreme temperature variations.

Conclusion

The BFC247952824 film capacitor is a reliable and versatile electrical component that has a wide range of applications. Its unique working principle and self-healing properties enable it to be used in high power equipment, power supplies, and high frequency applications. Its high voltage rating and long life make it a great choice for long-term use in high power circuitry.
