EEU-ED2C820B

Aluminum electrolytic capacitors are an important component in electronic circuits, which are widely used in power supplies, telecommunications, metering, instrumentation and other electronic circuits. The EEU-ED2C820B is a radial type aluminum electrolytic capacitor which incorporates Niobium Oxide dielectric and has exact specifications, such as dimensions and temperature range, as well as excellent features for long life and stable performance. This article will cover the application field and working principle of EEU-ED2C820B aluminum electrolytic capacitors.ApplicationsEEU-ED2C820B aluminum electrolytic capacitors are mostly used in low impedance, low ESR, high ripple current power supplies, such as switching power supplies. They are also frequently used in telecommunications and industrial control applications. In addition, they can be used in filter circuits as they offer high performance in both high frequency and low frequency operations. Finally, they are also useful in DC-DC converters with their low ESR at high frequencies.Working PrincipleEEU-ED2C820B aluminum electrolytic capacitors use a layered structure, consisting of an anode, a separator, and a cathode. The anode is made of a highly conductive aluminum oxide, while the cathode is made of relatively lower conductive Niobium Oxide. The capacitance value is determined by the area of these layers. In operation, charging current passes through the anode, while discharged current passes through the cathode. This current flow creates electric fields, and it is these fields that promote the transfer of electrons between the anode and the cathode. When the capacitor is exposed to high temperature or overvoltage, the life of the capacitor will be shortened due to heat generation and electrical breakdown. To ensure the safety and reliability of the capacitors, they should be incorporated with safety devices, such as a varistor and an overvoltage detection circuit. ConclusionIn conclusion, EEU-ED2C820B aluminum electrolytic capacitors are widely used in power supplies, telecommunications, industrial control and other electronic circuits. They offer high capacitance performance in both low and high frequency operation. Moreover, they are specifically designed to have a long life and stable performance even under harsh environmental conditions.
