Aluminum Electrolytic Capacitors

UVK1A471MED1TD aluminum electrolytic capacitors are suitable for filtering, frequency division, decoupling, and bypassing applications. They come in a variety of packages, in axial, through-hole, and surface-mount configurations, with a wide range of voltage and capacitance ratings.

Aluminum electrolytic capacitors are polarized components made up of two electrodes, an anode, and a cathode. The anode consists of a strip of aluminum foil etched to form a network of interconnecting passages and covered with a layer of an electrolyte-soaked paper or film. The cathode is a solid metal rod, and the two electrodes are inserted into a can. The entire assembly is then immersed in a potting material to form a complete capacitor.

The working principle of aluminum electrolytic capacitors is based on Faraday’s Law of Electrolysis, which states that when a voltage is applied to the electrodes, ions from the electrolyte are attracted to the respective electrodes and then deposited on the exposed surface area. This results in an increase in the effective surface area of the electrodes, which in turn results in increased capacitance.

The capacitance of aluminum electrolytic capacitors is affected by both the applied voltage and the features of the construction, such as the electrode surface area, type and thickness of the electrolyte, and the presence of a back plate. In addition, aluminum electrolytic capacitors typically exhibit a high self-inductance due to their construction, a factor that must be taken into account when using them in applications requiring high frequency signals.

Despite the fact that aluminum electrolytic capacitors come in a variety of sizes, their parts and components are often the same. This universal construction makes them easily interchangeable and allows for easy replacement of individual capacitors in an assembly.

UVK1A471MED1TD aluminum electrolytic capacitors are designed to provide reliable performance and long life in both high and low frequency applications. They are available in through-hole and surface mount packages, and come in various voltage and capacitance ratings.

Aluminum electrolytic capacitors are widely used in a number of industrial and consumer electronics applications, from power supplies and motor drives to audio and video equipment. Their low cost, wide range of available capacitance ratings, and ability to pass high-corresponding current make them a preferred choice for many design engineers.
