Aluminum electrolytic capacitors, such as ALS80A912NP350, are widely used in various electronic equipment such as switching power supplies, dc-dc converters, and audio amplifiers.

An aluminum electrolytic capacitor consists of two aluminum foils, a separator, and an electrolytic solution, all of which are enclosed in a casing. One of the aluminum foils, called the anode, is etched to form a large surface area and is then covered with a chemically formed film of oxide. The oxide acts as the dielectric layer that helps the capacitor store the electrical energy. The second aluminum foil, called the cathode, has aluminum electrolyte solution on it.

The way such a capacitor works is simple. When a voltage is applied between the two electrodes, the electrical charge is stored in the electrolyte solution which then creates an electric field across the dielectric layer. The electric field stores and increases the energy until the electrical charge across the dielectric layer has reached its maximum value. It is then discharged through the terminals of the capacitor.

Compared to other capacitors, aluminum electrolytic capacitors are widely used due to their advantages, such as high energy density, low cost, high stability and reliability, and long life. Additionally, they are capable of withstanding a wide range of temperatures, from - 40℃ to + 105℃ at normal humidity. With these advantages, aluminum electrolytic capacitors are suitable for a wide range of applications including power supplies, audio equipment, amplifiers, transducers, medical equipment, avionics, microcontrollers, and telecommunication devices.
