Its robust construction, high operating temperature range, and excellent performance make it an ideal choice for many applications.

The working principle of the B43455K0478M000 aluminum electrolytic capacitor is as follows. The capacitor is composed of two metallic plates (the anode and the cathode) separated by an insulating layer or dielectric. When a voltage is applied to the capacitor, the electrons from the anode are attracted to the cathode, and this creates an electric field between the two plates. This electric field stores energy in the form of an electric charge.

The capacitance of the capacitor is determined by the size of the plates and the thickness of the dielectric. The larger and thicker the plates, the higher the capacitance. The charge stored in the capacitor eventually dissipates as the current flows between the two plates. Due to its design, the B43455K0478M000 has a low dissipation factor, making it ideal for applications where power loss needs to be minimized.

In summary, the B43455K0478M000 aluminum electrolytic capacitor is a highly reliable and robust component with a 4.7μF capacitance value and a 450V maximum operating voltage. Its robust construction, higher operating temperature range, and excellent performance make it an ideal choice for many applications, such as power electronics, power supplies, inverters, and luminaires. Its working principle involves the attraction of electrons from the anode to the cathode, creating an electric field that stores energy in the form of an electric charge.
