Film Capacitors

The MKT1817268255G is one of the most common capacitors available in the market today. It is a film capacitor, meaning that it is a type of capacitor created by depositing metallic film onto a dielectric substrate. This capacitor is primarily used in medium to high voltage applications, providing robustness and much smaller size than other capacitor types.

Applications

Due to its strong tolerances and reliability, the MKT1817268255G is most commonly used in power electronics and lighting applications. In power electronics, film capacitors are used to store energy and as filters in power circuits to reduce electrical noise. In lighting applications, film capacitors are used for power factor correction and to add surge protection to circuits.

Additionally, film capacitors are often used in applications such as AC power supplies, automotive electronics, LED lighting, and even medical electronics. They are also often used to filter signal pathways in audio, studio, and broadcast equipment.

Working Principle

The working principle behind the MKT1817268255G is based on the charging and discharging of electrons between two layers of film separated by a dielectric material. The film on one side of the capacitor functions as the anode while the other is the cathode. When a potential difference is applied across the terminals of the capacitor, electrons flow from the anode to the cathode, creating an electric field.

When the potential difference is removed, the capacitor begins to discharge its charge. This charge is stored in the form of an electric field between the layers of film. The field strength is proportional to the amount of charge stored in the capacitor, thus allowing for current to be passed to the load when required.

Conclusion

The MKT1817268255G is a film capacitor which provides reliable performance and strong tolerances in medium to high voltage applications. It is most commonly used in power electronics, lighting, and even medical equipment. The capacitor works on the basis of charging and discharging electrons between two layers of film which is separated by the dielectric material inside the capacitor.
