What is an Aluminum Electrolytic Capacitor?

Also called an electrolytic capacitor, this capacitor uses liquid electrolyte as the role of cathode and aluminum oxide as dielectric. It features a large capacitance by forming minute unevenness on the surface of aluminum foil through electrochemical treatment to enlarge the surface area.

Super low ESR products, using solid conductive polymers instead of electrolytes, are also widely used. Hybrid capacitors, combining electrolyte and conductive polymers, have also emerged in recent years and aluminum electrolytic capacitors continue to evolve to provide optimal characteristics tailored to the conditions of use.

Although the life of this component is attributed to the evaporation of its electrolyte, its life can be expected to exceed ten years when used under the appropriate temperature conditions.
