Aluminum electrolytic capacitors are electronic components composed of two aluminum plates, separated by one or more layers of dielectric material. The most common type of aluminum electrolytic capacitor is polarized and has the anode formed from aluminum foil, with a thin oxide film that acts as insulation layer between the anode and the electrolytic liquid. The cathode is either a conductive heavy metal oxide film (usually tantalum pentoxide or niobium pentoxide) or a thick metal layer (usually nickel or gold). Aluminum electrolytic capacitors have two basic characteristics: their capacitance and working voltage. The capacitance of an aluminum electrolytic capacitor is directly proportional to the surface area of the anode and the thickness of the dielectric. The working voltage is determined by the dielectric and wax layer thickness and the electrolyte strength, and is usually in the range of 2-35V for most aluminum electrolytic capacitors.

E81D251VNN271MR25C capacitors are suitable for high frequency switching power supplies, voltage converter circuits and telecommunications equipment. They are used in applications that require low impedance and high peak current capability. These capacitors feature high capacitance ratings in a low profile package, excellent performance, low ESR, high ripple current capability, long life and low leakage current. Their small size and low impedance makes them ideal for decoupling high frequency switching power supplies, voltage converter circuits and other circuits requiring low ESR and high peak current capability.

The working principle of aluminum electrolytic capacitors is based on Faraday’s law of electrolysis, where an electrochemical reaction causes the aluminum plate to form a thinner oxide layer, which acts as the dielectric material between the plates. The voltage applied across the two plates, causes current to flow and ionizes the electrolyte, which then provides the elementary charges for the electric double layer at the oxide interface. This is the basic principle behind the capacitance of the aluminum electrolytic capacitors.

The main advantage of the E81D251VNN271MR25C capacitors is their low ESR and high ripple current capabilities. They can also be used in high precision and low profile applications. Their excellent performance and long life make them ideal for high frequency switching power supplies, voltage converter circuits and telecommunications equipment. The E81D251VNN271MR25C capacitors are ideal for use in a variety of applications.
