MKT1813310635 Application Field and Working Principle

Film capacitors are widely used for various power supply applications due to their low price and stable characteristics. Among them, Film capacitor MKT1813310635 is one of the most popular ones. This article will discuss the application field and working principle of MKT1813310635.

Application Field

MKT1813310635 is a film capacitor that is rated for more than 3 KV. It has an outstanding insulation resistance, high ripple current rating, and a long life. It is mainly used in high-frequency switching power supplies, high-frequency DC-DC converters, telecommunication equipment, alarm systems, and other applications that require EMI (Electromagnetic Interference) filtering. It is also widely used in high pulse & current circuits, high-speed rail, automotive systems, and electric vehicles.

Working Principle

MKT1813310635 is an electrolytic capacitor with a dielectric film between two electrodes. This film is composed of only a single layer of polyethylene terephthalate (PET) and a layer of metal oxide. An electrolyte is applied to the metal oxide film, which is then made into the shape of a rectangular paper bag and then sealed. Each layer is insulated from the other by dielectric material. Because each layer has a different dielectric constant, it has a unique feature called permittivity which allows the charge to travel through the film faster. This explains why the MKT1813310635 has such a low dielectric absorption.

In operation, the capacitance of the capacitor is created by the charge that is stored on each electrode. The charge is stored on the film when current flows through it, and this causes the charges to move back and forth between the poles of the capacitor. The higher the permittivity, the faster the charge can move between the electrodes. That\'s why the MKT1813310635 has such a low dielectric absorption.

The charge is also stored in the capacitor when there is a voltage difference between the electrodes. When the voltage difference between the electrodes becomes smaller, the charge stored in the capacitor is released slowly and the capacitance decreases. This is called a capacitance droop. The capacitance droop of the MKT1813310635 capacitor is very low, making it suitable for use in high frequency applications.
