Aluminum electrolytic capacitors, such as EEV-FK1C471GP, are components consisting of two or more aluminum oxide layers which sandwich a layer of pure aluminum foil. The aluminum oxide acts as an insulator that provides a static charge, while the aluminum foil serves as the two electrodes. The dielectric between the two electrodes is the electrolyte, which consists of a polarizable solvent, ions, and other additives, and provides the conducting path for the electrical current to flow from one electrode to the other.

The construction of an aluminum electrolytic capacitor, like EEV-FK1C471GP, is such that the thinner aluminum oxide layer adjacent to the aluminum foil electrode, called the cathode, is highly passivated, meaning it has a higher permittivity compared to the outer surface of the capacitor. The opposite charge of the aluminum foil electrode, called the anode, is correspondingly less permittivity rated.

The application of EEV-FK1C471GP includes usage as power supply, temporal storage, and noise suppression in consumer electronics, such as mobile phones, PCs, and cameras, among others. The capacitor offers a series of band-pass narrowing capability, snap-off response, and fast temperature changes, as well as a high level of capacitance.

The working principle of the EEV-FK1C471GP relates to the sum of the charge stored on the capacitors\' electrodes. When an electrical potential is applied across the two electrodes, a polarized field is created within the capacitor, which attracts ions from the electrolyte solution to the anode. This causes an accumulation of positive ions on the anode side and negative ions on the cathode side, resulting in a charge imbalance between the two sides.

The charge on the capacitor then consists of the sum of all the positive ions on the anode side and negative ions on the cathode. When a loaded voltage across the electrodes is removed, the accumulated positive and negative charges stored on the capacitor, both in the electrolyte and in the dielectric material, will gradually dissipate and the capacitor is discharged.

EEV-FK1C471GP aluminum electrolytic capacitors have a low cost, high energy densities, and low equivalent series resistance (ESR). The capacitor can handle relatively large current and voltage spikes, making it ideal for use in voltage-regulated power supplies, voltage stabilizers, and other power management applications. The capacitor also works well with many RF applications, such as for temporary storage of high frequency signals. Finally, these devices have a wide temperature range and are capable of operation over a wide range of temperatures, making them suitable for many applications.
