Aluminum electrolytic capacitors are polarized capacitors that use aluminum oxide (Al2O3) as the dielectric. It consist of two aluminum sheets loosely attached to each other by an oxide layer formed on both. The main components are an anode, cathode, electrolyte and a separator.

The B43540B5187M80 aluminum electrolytic capacitors are a type of surface mount power capacitors with capacitance values range from 2.5μF to 500μF. It is rated to operate at 4V and has a Kink voltage of around 4.7V. With the ESR of 0.22Ω it is suitable for high ripple current application. The sturdy plastic enclosure offers excellent protection against physical damage, making the B43540B5187M80 one of the most popular aluminum electrolytic capacitors in the industry. These capacitors are available in different sizes and forms including leaded, through-hole, snap-in and SMD packages.

The working principle of the B43540B5187M80 aluminum electrolytic capacitors is based on the Faraday law of electrolysis. The dielectric layer is made up of an aluminum sheet coated with an insulating oxide layer. The other sheet is the conductive plate which is connected to the outside source of electric power. The capacitor is filled with an electrolyte solution which carries electrically charged ions from the source of electric power to the conductive plate. It is these ions that are responsible for forming the dielectric layer.
