Aluminum electrolytic capacitors are used in a variety of applications such as motor control, electronic media, medical instruments, and power generation and distribution. Aluminum electrolytic capacitors are constructed with two aluminum foil electrodes, a layer of insulating material, and a spacer. The liquid electrolyte serves as an ion conductor between the electrodes. The combination of materials and process creates a large storage capacity in a small package.

A typical aluminum electrolytic capacitor consists of a cylindrical aluminum oxide dielectric that is sandwiched between two aluminum electrodes. The aluminum electrodes are etched with a thin layer of aluminum oxide which acts as the dielectric. The space between the two electrodes is filled with an electrolyte solution. The electrolyte is made up of an organic solvent, a cationically charged ion, and nitrates of the metal cations.

The 400USC100MEFCSN20X30 is an aluminum electrolytic capacitor. It uses an electrolytic layer formed by an anodized aluminum oxide layer between two aluminum electrodes. The electrodes are machined for optimal contact and the anodization layer is plated with copper. This combination of materials allows for a higher capacitance, extremely low ESR, and a self-healing behavior. The combination of low ESR and self-healing behavior make this capacitor a perfect choice for motor control applications.

The working principle of an aluminum electrolytic capacitor is based on the principle of an electrical double layer. When a voltage is applied to the capacitor, the two dielectric layers, the anodized aluminum oxide layer, and the organic electrolyte form an electric double layer in which electrons are stored in the dielectric layers. The charge stored in this double layer is proportional to the applied voltage. The amount of charge stored is directly proportional to the capacitance of the capacitor.

The 400USC100MEFCSN20X30 aluminum electrolytic capacitor is best suited for applications such as motor control, consumer electronics, audio systems, computers, automotive electronics, and power supplies. This capacitor provides high capacitance and low ESR, which makes it ideal for motor control applications. The self-healing behavior allows for high reliability in applications where the capacitor may be exposed to environments with high levels of transient voltages such as in automotive and consumer electronics. The low ESR and the combination of materials allow it to achieve a large capacitance in a small package.
