Aluminum electrolytic capacitors are widely used in many electronic circuits and systems due to their unique properties as high capacitance, high voltage, low cost, long life and reliable performance. They are formed with the combination of two aluminum foils, two electrolytic papers and aluminum oxide layer, which is formed through an anodic oxidation process of the aluminum against a liquid electrolytic medium containing special chemicals and acids. One aluminum foil acts as the plate of the capacitor, while the other foil acts as a connective bridge between the two sides to conduct current. An electrolyte is simutaneously induced between the two foils to enable the effective electrical operation. The aluminum oxide layer prevents any electrolyte leakage from causing a short circuit.

UEP1C221MPD is an aluminum electrolytic capacitor that comes with a non-solid electrolyte type. This type of capacitor is primarily used in high frequency pulse & reverse voltage applications. The maximum operating temperature for this type of capacitor is 105 degrees Celsius, and the peak reverse voltage is 200V. They are also available in different sizes and shapes, and they have high insulation resistance and withstand high temperature as well. The UEP1C221MPD capacitors have low leakage current compared to solid electrolytic screens.

The working principle of aluminum electrolytic capacitors is based on the different properties of the two separated aluminum foils. The area of one of the electrodes is in contact with the electrolyte. When a voltage is applied, ions are forced to move from the electrolyte and electroplate the surface of the metal section, forming a thin film layer of insulating oxide. This film of oxide increases the capacitance of the capacitor and prevents the electrolyte from being shorted due to current passing through the film. This also provides a stable working temperature for the capacitor and prevents degradation of performance due to excessive current passing through the film.

The UEP1C221MPD capacitor is widely used in circuits with power output, such as current amplifiers and power supplies; built-in amplifiers, speakers and audio systems; signal filters, switching power supplies and EMI filters. They are also used in medical devices such as blood pressure monitors, pacemakers, MRI scanners, patient monitors, infusion pumps and hearing aids. In addition, they are used in circuit applications for communication equipment, electronic service meters, automobiles, and data systems.

UEP1C221MPD capacitors have many benefits including high quality film systems, the ability to withstand large temperature ranges, low internal resistance, and high insulation. All of this makes this type of aluminum electrolytic capacitor an ideal component for many electronic circuits.
