MKT1817310015D

Film capacitors, sometimes referred to as film dielectric capacitors, are capacitors with one or more layers of plastic film as its dielectric medium. They are often used as filter components for AC and DC power supplies. The MKT1817310015D film capacitor is a kind of film capacitor that has been developed to meet the increasingly strict requirements of high-power transmission, where a reliable heat dissipation is required. The following will discuss the application field and working principle of the MKT1817310015D.

Application Field

The MKT1817310015D is a power capacitor with wide application in fields such as power electronics, radio broadcasting, high-power transmitted systems, communications, and renewable energies. Its special engineering designs make it suitable for applications in which high power and high temperature are concerned. On the one hand, its double deep sealed shell provides superior moisture and heat resistance and maintains a high capacitance stability at temperatures up to 125°C. On the other hand, it utilizes high-quality layers of polyester film and tin-plated copper terminals, which offer an excellent heat dissipation. This makes the MKT1817310015D suitable for environments with extreme conditions.

Working Principle

The MKT1817310015D film capacitor works on the principle of polarization and dielectric phenomena. Its working principle is closely related to the molecular properties of the dielectric medium, such as polarity and dielectric constant. Polarization occurs when an electric field is applied to the dielectric medium, with the atoms of the medium aligning themselves in the direction of the field. The polarization creates an electric field around the capacitor, which is what creates the capacitance. This capacitance is further increased by the dielectric constant of the dielectric material, which is a measure of the material’s ability to oppose the electric field. The higher the dielectric constant of the dielectric material, the higher the capacitance of the film capacitor.

In conclusion, the MKT1817310015D is a film capacitor developed for applications requiring high power and heat dissipation. Its double sealed shell and high-quality layers of polyester film and tin-plated copper terminals realize an excellent heat dissipation and a high capacitance stability. Its working principle is based on the polarization and dielectric properties of the dielectric medium, which is further enhanced by the high dielectric constant of the dielectric material.
