Aluminum electrolytic capacitors (ECs) are widely used in electronic circuits for their high capacity and efficient filtering performance. ECs are mostly cylindrical, with two continuous electrodes connected by a thin-film dielectric. They usually operate in two modes: dielectric and metal electrolyte.

In the dielectric mode, an electric charge is supplied to the two electrodes, resulting in a buildup of an electric field between them. This field induces physical distortion in the diaphragm, effectively increasing the area and using the charge to attract and hold an electric charge. The amount of charge stored depends on the thickness of the diaphragm and the voltage applied, typically ranging between 1 to 18 Volts. The stored charge is then discharged when the device is powered off, providing a filtering effect to remove power spikes and interference.

In the metal electrolyte mode, the electrolyte is injected between the two electrodes. The electrolyte, composed of lead or other metals, acts as a conductor, allowing for a more efficient transfer of electrical charge. The amount of charge stored and released in an EC is significantly higher in this mode, ranging from 2 to 36 Volts. The higher storage capacity makes ECs ideal for use in higher voltage circuit applications.

ECs are available in a variety of sizes and shapes, and may contain a range of specific features, depending on the intended usage. Generally, they consist of two flat metal plates, with an insulating paper between them and a thin dielectric film between them. The outer environment is isolated from the internal environment by a gasket or seal, allowing for reliable operation in a variety of environments. The electrodes may be designed using a variety of materials, including silver, nickel, aluminum and even ceramic, to provide the highest electrical conductivity. Some ECs may even be constructed from several different layers of material, allowing for greater control of the electrical properties and minimizing losses in thermal transfer.

The 861101487034 is an example of a type of EC commonly used in vacuum applications, such as in vacuum tubes. It is designed to operate at high voltages (up to 2000V in some cases) and at low temperatures. The design incorporates a dielectric layer composed of insulating paper and silver metal electrodes, allowing it to withstand high temperatures and effectively filter power spikes. The 861101487034 is also engineered to minimize losses in thermal transfer, providing greater efficiency and stability.

In conclusion, the 861101487034 is an example of a unique and highly capable Aluminum Electrolytic Capacitor, providing an ideal combination of high storage capacity, efficient filtering performance and reliable operation. When used in vacuum applications, it is capable of filtering power spikes and dealing with thermal transfer with minimal losses. This makes it an ideal choice for a variety of high voltage applications.
