Film Capacitors

Film capacitors are a type of capacitor used in many applications, such as broadcast and audio, power electronics, energy storage, automotive, and industrial controls. They are made of plastic film coated with a thin film of metal, usually aluminum, to form a capacitor.

MKT1822222105

The MKT1822222105 is a flexible film capacitor designed primarily for power electronics, automotive, and industrial applications. It is a metalized polypropylene member of the MKT18 series of film capacitors. This capacitor has a plastic or metalized enclosure with a lead-free construction. It also features a wound construction for excellent performance in high frequency applications.

Application Field

The MKT1822222105 is ideal for various applications requiring high levels of reliability and stability such as power conditioning, harmonic filtering, and motor control. It is also suitable for a wide range of high voltage and high power operations, such as high input voltage AC/DC converters, high current rectifiers, inverters, and motor drives.The MKT1822222105 is an excellent choice for automotive applications, such as electric vehicles, electronic ignition systems, and battery charging systems. It offers excellent operational performance due to its self healing property and high voltage rating.

Working Principle

The MKT1822222105 is a metalized plastic film capacitor and consists of two closely spaced and parallel electrodes, separated by a small dielectric layer. The metalized electrodes are usually formed from a metal film (generally aluminum) and coated on both sides of the film with an insulating layer. This capacitor has a flexible construction and is less prone to mechanical damage.The capacitor works by storing electrical charge in its dielectric layer. When a voltage is applied to the electrodes, the electric field in the dielectric attracts free electrons, which move to the positive electrode. This generates a charge opposite in polarity to that of the applied voltage. As a result, an electric field is created that opposes the applied voltage, stopping the flow of current.

Conclusion

The MKT1822222105 is a highly reliable flexible film capacitor with a number of applications in various areas, such as power electronics, automotive, and industrial. It is specially designed for high voltage and high power operations and its self-healing property ensures long service life. Its working principle is based on storing electric charge in its dielectric layer that generates electric field opposing the applied voltage, blocking the current flow.
