Film capacitors are one of the most popular types of capacitors which are widely used in digital circuitry. The MKT1813247636G is one such film capacitor and its application field and working principle should be understood well to make best use of it.

This MKT1813247636G film capacitor has multiple applications, including the use in motor drives, high-frequency power supplies, uninterrupted power supplies (UPS), switch-mode power supplies (SMPS) and resonant circuits. It also finds application in automotive applications such as fuel injectors and sunroofs, and it is also used for telecommunication components. Being a non-polarized capacitor, it is suitable for AC and high pulse current applications.

The MKT1813247636G film capacitor has a base film that consists of a polyester film and special epoxy resin. The film is coated with a thin metal oxide layer, over which a layer of conductive material is applied. This conductive layer is usually made of electrolytically deposited metal or carbon sprayed onto the film dielectric. The metal or carbon is then patterned to get the desired shape.

The working principle of a film capacitor is relatively simple. A film capacitor works on the principle that electrons flow from one metal layer to another when an electric charge is applied. When two layers are separated by a thin dielectric film, they form a capacitor. When an AC voltage is applied to the film capacitor, electrons flow from one metal layer to the other through the dielectric medium, creating a storage of electric charge. Depending on the frequency of the voltage, a certain amount of charge is stored in the capacitor cells.

The MKT1813247636G film capacitor is highly reliable and stable over a long period of time. Its limitation on reactive power makes it suitable for continuous operation in a wide range of temperature. Its high density metallization provides high capacitance with low equivalent series resistance (ESR). Another advantage of this capacitor is its small size, which allows for smaller and more efficient circuitry. With its high stability, low ESR and high operating temperature, this film capacitor is an excellent choice for power supply components.
