Aluminum electrolytic capacitors are a type of capacitor that utilizes an electrolyte as one of its two electrodes. These capacitors contain a non-aqueous electrolyte, such as a polymer or amorphous carbon, as the dielectric between the two metal plates. The aluminum electrolytic capacitor is generally considered a polarized capacitor, meaning that one plate is positive and the other plate is negative. Unlike other types of capacitors, the aluminum electrolytic capacitor exhibits a much higher capacitance in a smaller size.

EEV-EB2W100SM is an aluminum electrolytic capacitor product of EverElettronica. It has excellent performance for commercial and industrial applications.

In IT equipment, it can be used in servers, personal computers and telecommunications equipment. In LED lighting, it is used in downlight, panel light, flexible light strips, floodlight and high bay lights.

Working Principle

The working principle of aluminum electrolytic capacitors is similar to other capacitors. It works by storing electric charge between its positive and negative electrodes. The positive and negative electrodes are usually formed of aluminum foil, on to which an insulating film called dielectric is placed. The dielectric is made of a non-aqueous electrolyte, such as a polymer or amorphous carbon. An electric current is then passed through the electrolyte, causing the sandwich of electrodes and electrolyte to become polarized. This polarization of the electric field causes the electrolyte to become a dielectric, producing the capacitance.

In the case of EEV-EB2W100SM, the aluminum foil electrodes are coated with an anionic film of aluminum oxide. This aluminum oxide acts as a barrier to the electrolyte, preventing direct contact between the two electrodes and promoting a higher capacitance. This type of capacitor also has a unique self-healing feature, meaning it is able to recover from any short-circuits or voltage surges caused by inrush current.

The capacitance of an aluminum electrolytic capacitor varies with temperature, with higher temperatures causing the capacitance to decrease. For the EEV-EB2W100SM, the tolerable temperature range is -40℃ to 105℃, meaning that the capacitor remains within its rated capacitance for temperatures within this range.

The EEV-EB2W100SM is a high-quality aluminum electrolytic capacitor, ideal for a variety of commercial and industrial applications. Its excellent performance and small size make it an ideal choice for power supplies, ac/dc converters, audio equipment and other electronic systems.
