Working Principle of SEK470M063ST

The SEK470M063ST is an electrolytic capacitor which utilizes an electrolyte solution impregnated between two layers of metal foil electrodes. The electrolyte solution provides the electrical connection between the two metal foils and is used to store the energy. The metal foils of the capacitor are separated by a non-conductive material such as paper or plastic which prevents any direct electrical contact between the two electrodes. When a voltage is applied to the capacitor, the current flows from one electrode through the electrolyte solution to the other electrode. During this process the electrolyte solution breaks down and deposit its ions on the metal foils, creating an electrical charge in the capacitor.

The energy stored in the capacitor is proportional to the charge on the electrodes. When the capacitor is discharged, the voltage across the terminals reduces and the electrolyte solution recombines to form the electrolyte solution. This process is reversed when the capacitor is charged again. The SEK470M063ST capacitor is designed to be resistant to damage from high rates of charge and discharge, and is capable of withstanding temperature extremes.

Conclusion

The SEK470M063ST aluminum electrolytic capacitor is a miniature component which is suitable for high power applications where size is a constraint. It has a wide range of applications, including audio crossover networks, grade switchers, echo cancellers, PLL circuits, and current filters. It also has a high ripple current which allows it to withstand temperature extremes.
