Aluminum electrolytic capacitors are electrical components typically composed of two or more aluminium foils which are rolled into a cylindrical shape and sealed in a metal can. A layer of organic material such as paper, plastics or rubber is used as a separator to prevent the two conductors from coming into contact with each other. A liquid or solid electrolyte, often a form of sulfuric acid or organic solvent, is used to fill the gap between the electrodes. UBT2E680MHD, an aluminum electrolytic capacitor, specializes in ultra-high capacitance values and is ideal for use in power management applications.

The UBT2E680MHD is designed to meet the sophisticated power management requirements of space-constrained and high-reliability applications. This aluminum electrolytic capacitor utilizes a double-long foil design, which allows for a larger effective surface area and higher capacitance values than single-sided foil capacitors. The use of a high-temperature electrolyte enhances the capacitor\'s stability over temperature changes, with a rated temperature range of -55°C to +105°C. The diameter of the UBT2E680MHD is 18mm and its length is 30mm, making it ideally suited for use in tightly packed, high-density circuits.

The working principle of the UBT2E680MHD aluminum electrolytic capacitor is based on the formation of a thin oxide layer on one or both of the capacitor\'s anode foils. This oxide layer is formed in the manufacturing process and is insoluble in the electrolyte. When a voltage is applied to the capacitor, the anode foil closest to the anode develops a higher electrical potential, which attracts cations present in the electrolyte to it. These cations then become attached to the oxide surface, releasing electrons. The movement of these electrons to the anode increases the capacitance of the capacitor.

The UBT2E680MHD aluminum electrolytic capacitor is an ideal choice for use in a variety of power management applications. It is well-suited for applications where ultra-high capacitance values are needed, such as DC/DC converters, discharge circuits, and low-noise filter circuits. Its high capacity helps to ensure a reliable supply of energy and its low impedance characteristic helps to reduce circuit noise. The use of a high-temperature electrolyte minimizes changes in capacitance over temperature, ensuring consistent performance in extreme environmental conditions. In addition, its small size makes it well-suited for use in high-density applications.
