Working Principle

The B32913A4473M000 capacitor is based on a dielectric material that is made from multiple layers of plastic film. The dielectric material is sandwiched between two layers of metal electrodes, usually made from copper, which act as the two plates of the capacitor. The dielectric material is selected according to the application. The characteristic of the film capacitor is determined by the type and thickness of the dielectric material used in the construction.

When a potential difference is applied across the electrodes, an electric field is produced, which causes electric charge to accumulate on the metal plates. This charge results in a capacitance value that is determined by the type and thickness of the dielectric material. The capacitance of the capacitor is directly proportional to the surface area of the plates and inversely proportional to the distance between them.

The B32913A4473M000 capacitor is a high-frequency capacitor due to its capability to hold charge even at high frequencies. Its dielectric material has high dielectric constant and lower dielectric loss. This enables it to offer higher capacitance at higher frequencies, allowing it to operate even at extremely high frequencies. This property makes the capacitor suitable for high-frequency applications.
