Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are highly important components in electrical and electronic devices. This type of capacitor is used for a variety of different applications ranging from power supplies, audio, lighting and telecommunications to industrial applications. They are the most common type of capacitor and come in a wide variety of shapes, sizes and capacitance values.Aluminum electrolytic capacitors are made from two components, a metal can (usually aluminum) and an electrolyte solution. A thin layer of metallic foil is added between the can and the electrolyte to increase the capacitance. The can acts as the body of the capacitor and the electrolyte solution seals the capacitor against moisture and air. The main purpose of aluminum electrolytic capacitors is to store electrical energy. They are used in circuits to filter out noise and interference, to adjust the gain and phase advance of signals, and to smooth the current in high power applications. These capacitors are also used to maintain a steady voltage in circuits with large current draw to protect the components from damage. When it comes to applications, aluminum electrolytic capacitors are used in a wide range of applications from audio, telecommunication, automotive, military/aerospace and power supply systems.
