Aluminum electrolytic capacitors, also known as electrolytic capacitors or electrolytic cold storage capacitors. They are from the earliest developed electro-polished aluminum foil and the paper soaked in electrolyte to form a pair of parallel electrode plates, which are our most commonly used capacitors. The large capacitance, low price and reliable performance of aluminum electrolytic capacitors make them widely used. The LLS1V822MELA is an example of an aluminum electrolytic capacitor.

LLS1V822MELA is a radial leaded aluminum electrolytic capacitor with a maximum rated voltage of 16V and a capacitance of 22YF. The LLS1V822MELA is used in a variety of electronic devices and consumer electronics, such as LED lighting, home appliances, digital products, communications and audio / video equipment.

In most electronic devices and consumer electronics, capacitors are usually used to store electrical energy and regulate the flow of energy. The main purpose of the aluminum electrolytic capacitor is to maintain energy and reduce ripple, that is, the supply of the lamp, or the purpose of the pulse coupling. This requires that the capacitor has a large capacity and low ESR, so that the load can be supplied with electricity for a long time.

The working principle of aluminum electrolytic capacitors is quite simple. The electrodes of the capacitor are two aluminum foil interspersed with paper soaked in electrolyte, forming two electrically isolated electrodes, forming a sign +/-. When a voltage is applied between the two, a strong electric field acts on the aluminum foils, which chemically converts the aluminum atoms on the surface of the aluminum foil into an oxide film, forming a dielectric film, forming an insulated anode foil. This dielectric film has the characteristics of polarized capacitance, which can realize the function of energy storage.

In this way, an electrical double-layer capacitor is formed. The anode oxide dielectric layer and the electrolyte form a very thin electric double layer, which is connected to the negative electrode, and this layer can store electrical energy. At the same time, the electrolyte provides ion flow, and the current carrier contributes to the charge transfer of the capacitor and the realization of energy storage.

In summary, the LLS1V822MELA is a radial leaded aluminum electrolytic capacitor with a maximum rated voltage of 16V and a capacity of 22UF. It has a wide application field, mainly used for energy storage and ripple reduction in a variety of electronic devices and consumer electronics. The working principle of aluminum electrolytic capacitors is quite simple, two aluminum foils and electrolyte form an electrical double layer capacitor, which can store electrical energy.
