Working Principle

The SFP28S48L375K-F consists of two or more metalized layers of film which are laminated with a dielectric material. The film is formed by stretching it and coating it with tin oxide, aluminium oxide, or tantalum pentoxide. The two or more metalized layers of film form an harmonizing type capacitance where the successive layers form capacitors which are connected in series with one another.

When a voltage is applied across the capacitor, the dielectric material acts as an insulator and prevents the flow of electrons from one layer to the other, allowing a current to flow through it. This current creates an electrical field between the two layers and stores energy in the form of a charge. The capacitance of the capacitors depends on the area of the dielectric and the thickness of the layers.

The SFP28S48L375K-F is also suitable for operations up to 1 GHz and it has a small size. It is designed for high frequency applications that require high power or a low equivalent series resistance and is capable of high current handling, low dielectric losses, and a high insulation resistance.
