Aluminum electrolytic capacitors are a kind of capacitors composed of aluminum foil substrate, inorganic oxide film as dielectric and electrolyte liquid as electrodes. They belong to the category of polarized capacitors due to their special structure and working principle. The ALS71H164QC040 is a kind of aluminum electrolytic capacitor developed by Foshan YuHang Electronic Co., Ltd. This capacitor has many application fields and working principles.

Application Fields of ALS71H164QC040

The ALS71H164QC040 aluminum electrolytic capacitor is mainly used in power electronics, such as rail transit, high-27 power switching power supplies and inverters, frequency drives, uninterrupted power supplies and so on. It also fits electrical equipment and home appliances, such as audio, DVD players, projectors, printers, washing machines and other industries. In addition, it is also widely used in welding machines, lighting fixtures, automotive and other related industries.

Working Principle of ALS71H164QC040

The ALS71H164QC040 aluminum electrolytic capacitor is mainly composed of three parts, namely, a metal core, a dielectric film and an electrolyte. The main principle of its work is that the dielectric and the electrolyte can form a large capacitance, while the metal core has the function of heat dissipation. The inner wall of the capacitor is made of aluminum foil, and the medium inside is a mixture of electrolyte and organic oil. When the capacitor passes through current, the electrolyte and the organic oil molecules are broken down, which results in many positive and negative ions.

When particles with the same charge are moved to the surface layer of the dielectric film, a negative surface charge in the dielectric is generated, and the electrons in the outer foil of the capacitor begin to move in one direction. At this time, electron flow is generated in the electrolyte conduction system. Therefore, an electric field is generated between two layers, and the electric field is used to create a storage energy. This electric field is very effective at controlling the current. When the voltage is removed, the accumulated energy will be released in the opposite direction.

Advantages of ALS71H164QC040

The ALS71H164QC040 aluminum electrolytic capacitor has many advantages. First, due to its compact structure, it occupies less space and provides a large capacitance.
