Film Capacitors

Capacitors are electrical components that are used to store energy in an electric field. The MKT1817210405G is one type of film capacitor, specializing in high-precision and high-quality applications.

What is a Film Capacitor?

A film capacitor is a type of capacitor that uses a thin film as a dielectric material between two conductive electrodes. The film can be made from polypropylene, polyester, polycarbonate and polyphenylene-sulfide. Each type of film has its own advantages and disadvantages, so the best option should be chosen based on the required application.Film capacitors have low inductance, low ESR (equivalent series resistance), high insulation resistance and high-temperature stability, making them well-suited for applications in high-fidelity audio and power electronics.

MKT1817210405G Application Field and Working Principle

The MKT1817210405G is a polypropylene film capacitor suitable for high-precision and high-quality applications. It is particularly suited for use in AC applications, audio applications, and DC blocking and by-pass circuits.The MKT1817210405G works on the principle of electrostatic charge or differential voltage. This film capacitor consists of two electrodes: an a-side and a b-side. The differential voltage between these two electrodes creates an electric field that can store energy. The dielectric material of the film separates the a-side and the b-side, preventing the current flow between them until the electric field becomes strong enough to overcome the dielectric material’s insulation.The MKT1817210405G has low leakage and can be used in applications where precise DC blocking is required, such as in audio filtering and power supplies.

Conclusion

Film capacitors are useful components for applications that require precise DC blocking, low inductance and low ESR, and high insulation resistance. The MKT1817210405G is one such film capacitor, made from polypropylene and offering high-precision and high-quality performance. Its applications include AC, audio and DC blocking circuits. By understanding the working principle of film capacitors and the advantages of the MKT1817210405G, engineers and designers can make the best choice when selecting a film capacitor for their next project.
