Introduction

Aluminum electrolytic capacitors are devices that are used to store electrical energy, electric field and current. They are composed of two aluminum or aluminum alloy plates that are separated by an electrolyte which serves as a capacitor dielectric. An aluminum electrolytic capacitor consists of an anode (positive) and a cathode (negative), which are separated by a separator and filled with an electrolytic solution. The anode of the capacitor is typically made from aluminum foil, while the cathode is made from an activated carbon material. Aluminum electrolytic capacitors have several advantages over other types of capacitors, such as excellent dielectric strength and high voltage stability. For these reasons, aluminum electrolytic capacitors are commonly used in numerous applications such as automotive electronics, energy storage, audio electronics, computer systems and consumer electronic devices.

Application Field and Working Principle

Aluminum electrolytic capacitors are used in numerous applications, including automotive electronics, energy storage, audio electronics, computer systems and consumer electronic devices. Some of their most common uses include: filter capacitors, filter sections for frequency-dependent circuits, start capacitors for motor applications, and in various switching power supply circuits. Aluminum electrolytic capacitors are also used to store energy for applications such as flash units, mobiles, cameras, and other electronic equipment.

The working principle of a aluminum electrolytic capacitor is based on the fact that whenever a potential difference is applied across two conductive plates an electric field is created. This electric field causes an electric charge to be stored in the capacitor. When the applied potential difference is increased, the electric field increases until it reaches the limit of the dielectric, causing the capacitance to increase and the capacitance values to reach their highest values. When the applied potential difference is lowered or removed, the electric field dissipates, resulting in a decrease in the stored energy and a decrease in the capacitance values.
