Film Capacitors

Film capacitors are a type of capacitor used to store energy as electric charge in an electric field. They come in a variety of types and are typically found in audio, video, RF, and other electronic applications. The film capacitor is made of a thin plastic film or a special paper with both electrodes placed on the film. This type of capacitor offers excellent performance characteristics, is highly reliable, and is used in many industrial and consumer applications.The DME2S27K-F film capacitor is a particularly advanced film capacitor. It offers a unique combination of low ESR, high capacitance, and high dielectric strength. It is also highly reliable, with a long service life and excellent frequency stability.

Application Field

The DME2S27K-F film capacitor is suitable for a variety of applications, including general audio/video, automotive, power, and medical electronics. It has a low ESR of 0.05 ohms, so it is well suited for DC to AC conversion in an AC adapter. It can also be used in DC power supply circuits and power factor correction.Other applications include DC-DC converter circuits, capacitor arrays, surge current suppression, and electromagnetic noise suppression. The capacitor\'s high dielectric strength makes it ideal for high harmonic suppression, while its excellent frequency stability makes it suitable for both conventional and modernized systems.

Working Principle

The DME2S27K-F film capacitor is a metallized film capacitor. Inside the capacitor, a thin plastic film (typically PTFE) is coated with an electrode material. The film is then sandwiched between two metal electrodes, and a dielectric coating is added to prevent short circuits.When voltage is applied, the capacitor stores energy as electric charge in an electric field between the electrodes and the dielectric. The capacitor\'s capacitance—or the ability to store charge—depends on the surface area of the electrodes, the distance between them, and the dielectric strength of the film.The DME2S27K-F has a large capacitance in a small package and superior operating characteristics, making it suitable for a variety of applications. Its low ESR, high capacitance, and high dielectric strength give it outstanding performance, making it a reliable choice for many types of circuits.
