Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, also known as an electrolytic capacitor, is an electrolytic capacitor with aluminum electrodes. It is composed of an anode and a cathode, separated by a paper-like dielectric membrane and a liquid electrolyte. This powerful capacitor was invented in the early twentieth century, and is since then made of a foil-like anode of aluminum, that is oxidized to form a very thin insulating layer. The electrolyte, a liquid or gas, acts as the second electrode.

The aluminum electrolytic capacitor is widely used due to its long life and low cost. The capacitor combats issues of noise, temperature, and voltage with an excellent impedance-temperature characteristic which makes it an ideal choice in applications that need a very high impedance and a low ESR. These capacitors have a wide range of applications, including in power supplies, signal processing, and audio and video systems.

381LX102M200J052 application field and working principle

The 381LX102M200J052 aluminum electrolytic capacitor is a capacitor used to store electrical energy and reduce power line harmonics. It has a low impedance and a wide operating temperature range, and it is used in a variety of power supplies, including ac-dc, dc-dc and adjustable variable power supplies.

Its working principle is based on Faraday’s law of induction, which states that a voltage is induced in a circuit when it experiences a changing magnetic field or a change in current flow. The capacitor consists of an anode and a cathode, each composed of aluminum foil with an oxide layer. A thin layer of dielectric electrolyte is applied to one side of the foil, and a liquid electrolyte is inserted into the capacitor.

When a voltage is applied to the capacitor, the negatively charged cathode attracts the positively charged ions in the electrolyte, causing them to be deposited onto the anode. As current is sent through the capacitor, a layer of electrons accumulates on the anode, creating a capacitor with a built-in charge. The charge is then stored as electrical energy and can be used as required.

The 381LX102M200J052 aluminum electrolytic capacitor is a polarized capacitor, which means it can only be connected in one direction. It also has a lower self-discharge rate than other types of capacitors, making it an excellent choice for applications with frequent on/off cycles. It is also commonly used in AC motors, electrical meters, remote control circuits, switching power supplies, and general power circuits.

In summary, the 381LX102M200J052 aluminum electrolytic capacitor is a powerful electrical component capable of storing electrical energy and reducing power line harmonics. It has a low impedance, a wide operating temperature range, and it is often used in power supplies, AC motors, electrical meters, remote control circuits and general power circuits.
