Film Capacitors

Film capacitors, also known as film dielectric capacitors, are polarized capacitors with a dielectric film made of polyester (PET), polycarbonate (PC), polypropylene (PP) or polysulfone (PES). They have very high insulation resistance as well as excellent dielectric properties and are widely used in high-frequency and power applications such as TVs, radios, and digital products. The MKT1818333256 is a lightweight, low-cost, and reliable film capacitor that offers excellent electrical characteristics and is suitable for a variety of applications.

Application Field

The MKT1818333256 is a low-cost and lightweight film capacitor that is suitable for a wide range of applications. It has excellent electrical characteristics and is designed for use in high-frequency power supplies, motor drives, and other AC applications including high-end consumer electronics, medical, and automotive applications. The capacitor’s small size makes it suitable for applications requiring a small as well as low-cost solution. Additionally, its low ESR and low inductance make it particularly suitable for switch-mode power supplies and high-frequency switching applications.

Working Principle

A film capacitor consists of two thin metal electrodes separated by a thin dielectric film. When a voltage is applied to the electrodes, an electric field is created in the dielectric film, which opposes the applied voltage. This creates a capacitance between the two electrodes. The ability of the dielectric material to resist the electric field is referred to as its dielectric strength, and it is one of the most important characteristics of film capacitors. The MKT1818333256 is designed to offer high dielectric strength for good performance in demanding applications.

The electrical performance of a capacitor depends on its ability to store and release energy when the voltage is changed. Since a film capacitor has a thin dielectric film, it can quickly and efficiently store and release energy. As a result, it has a low equivalent series resistance (ESR) and low inductance, which makes it suitable for high-frequency applications. Additionally, its low ESR and low inductance make it good for switch-mode power supplies and high-frequency switching applications.

The MKT1818333256 is designed to provide a reliable and high-performance film capacitor solution. The capacitor is designed to withstand high operating temperatures and is RoHS compliant. Additionally, the capacitor is fully sealed in a thermoplastic housing to ensure it is dust and moisture resistant. This makes it suitable for applications requiring extreme conditions, such as automotive or outdoor applications.
