Film capacitors are a type of capacitor that utilizes a film as a dielectric, making them flexible and highly efficient than other types of traditional capacitors. The MKT1817227254G film capacitor is an aluminum electrolytic film capacitor that has a high capacitance, low ESR and is highly reliable. It has a small size, low equivalent series resistance and high temperature stability, making it suitable for a wide range of applications where high capacitance, large current, and long life are required.

Application Fields

MKT1817227254G film capacitors are widely used for high voltage, large current, and low ESR applications such as power supplies, DC-DC converters, switching power supplies, AC DC converters, high precision digital circuits, and so on. It also finds application in military, medical and communication devices, audio/video systems, high temperature and/or harsh environment applications, and more.

Working Principle

The MKT1817227254G film capacitor works on the principle of capacitance, which is the property of the capacitor to store electrical energy in its electric field. It works in the same way as a traditional capacitor, but with a different dielectric material. The film used as the dielectric material is typically a polyester or polypropylene film which provides a higher capacitance than the typical dielectric material used in traditional capacitors. Furthermore, this film material has a low ESR and high temperature stability, making it an excellent choice for a wide range of applications.

The MKT1817227254G film capacitor consists of two conducting electrodes separated by a dielectric material, typically a polyester or polypropylene film. The two electrodes are separated by a thin insulating layer which helps to reduce the ESR and improve capacitance stability. The capacitance of the film capacitor is determined by the area of the two conductive plates, the thickness of the dielectric material, and the type of material used (polyester or polypropylene).

When an electric field is applied between the two electrodes, the dielectric material experiences a change in its electrical properties and this allows the capacitor to store energy. The electrical energy is stored by creating an electric field between the two conductive plates, which forces electrons to move from one plate to the other, thus creating a charge differential. This charge differential can be tapped by connecting the two electrodes of the capacitor to the power supply, allowing the capacitor to provide current when the voltage is applied to it.

The MKT1817227254G film capacitor has a wide range of applications due to its high capacitance, low ESR, and high temperature stability. It can be used in a variety of applications, such as power supplies, DC-DC converters, high precision digital circuits, and so on. Its small size and high performance makes it a great choice for applications where high current and long life are required.
