Aluminum Electrolytic Capacitors are widely used in various applications. The LLS2G391MELB is one such type of capacitors. It’s construction and working principle is specifically created for high-performance use in a range of fields.

Construction

The LLS2G391MELB is a large cylindrical package with two electrical leads that protrude from the package and are used for connection. The capacitor is filled with a liquid electrolyte which is contained between two aluminum foil plates which together are called an electrolyte’s “dielectric”. This dielectric is placed between two aluminum sheets stamped to form a spiral shape. A band of conductive material wraps around the cylinder and also serves as an electrical connector between the internal electrolyte and the external electrical leads.

Working Principle

The basic principle behind LLS2G391MELB is the same for all Aluminum Electrolytic Capacitors. They maintain a charge by having their internal electrolytic solution react with electrodes, forming a dielectric insulator between the two. As the electric current flows in and out, the positive and negative ions attach and detach themselves to the electrodes, forming an electrical charge. This occurs through the electrolyte’s conductivity, which is a result of its chemical composition. The operating voltage of the capacitor is limited by the electrolyte’s breakdown voltage.
