Aluminum Electrolytic Capacitors: LLS2V151MELA Application Field and Working Principle

Aluminum electrolytic capacitors (AECs) are a type of capacitor with a polarized electrolyte composed of an anode, a solid porous cathode and metal oxide film. They store electrical energy through electric field polarization; that is, electrical charges stored on the electrolyte surface. AECs are highly efficient for use in power electronic circuits, making them beneficial for a wide variety of applications. The LLS2V151MELA is one of the many AECs available for use with today\'s electronics.

AECs have three main components: an anode, a cathode, and a solids phase source layer. The anode is composed of a massive volume of roughly-cut aluminum foil that is immersed in an electrolyte solution. The electrolyte solution is a mixture of acid and water that creates an electric field when electrons flow between anode and cathode. The electric field polarizes the electrolyte surface, forming an electric double layer between the electrodes. The electric field also induces a Faradaic reaction at the anode, which allows for charge storage.

The Cathode comprises of a metal oxide film that forms exclusively on the Si-SiO2 interface. This film acts as the capacitor\'s dielectric. The capacitance of a capacitor is determined by the surface area of the metal oxide film, which increases with a greater amount of electrodes. The solids phase source layer provides an alternative source of electrons for charge-storing within the electric double layer.

The LLS2V151MELA AEC is specifically designed for use in power electronic circuits. This type of capacitor has a relatively high capacitance-to-volume ratio, making it ideal for applications where space is limited.
