FILM CAPACITORS

MKT1820518256 application field and working principle

Film capacitors are a type of capacitors that use a thin film of plastic to create capacitance between two metal plates. The two primary types of these capacitors are metallized film capacitors and thermally-stabilized film capacitors. The MKT1820518256 is a type of film capacitor whose capacitance range makes it suitable for various power applications including electricity power supply and power supply regulation.

The MKT1820518256 is made using a metallized polypropylene film which has a long molecular chain structure and an advantageous breakdown field. A metal layer is formed on one side of the film, which is then amalgamated with the conductor section. The material is then wound and encapsulated in a protective sleeve. The result is a capacitance range of 18 pF to 205 pF, with a voltage range of 18 V to 18 V.

The MKT1820518256 features various advantages over other types of film capacitors including high dielectric strength, which makes it suitable for power supply derating or power factor correction, as well as improved insulation resistance and heat resistance. It also has a low equivalent series resistance and inductance, as well as low leakage current.

Film capacitors, such as the MKT1820518256, have a variety of applications in the power industry. They can be used in power lines, as well as in the manufacture of electrical appliances and for the design of power supply systems. In addition, film capacitors are often used in surge protectors, as well as in power line conditioning, decoupling, and other power-conditioning applications.

The working principle of a film capacitor is relatively simple and involves the use of two metal plates, one of which is attached to an insulated film. This film acts as a dielectric between the two plates, allowing them to store an electric charge and creating capacitance. When a voltage is applied, it causes an electric field to form between the two plates, allowing the capacitor to store electrical energy.

In summary, the MKT1820518256 is a type of film capacitors whose capacitance range makes it suitable for various power applications. It features a range of advantages including improved insulation resistance and heat resistance, as well as low equivalent series resistance and inductance. These capacitors have a variety of applications in the power industry, and the working principle involves the use of two metal plates, one of which is connected to an insulated film.
