Aluminum Electrolytic Capacitors (AECs) are a type of capacitor used in many electronics applications. The ECE-A1VN471UB is an AEC with a maximum operating temperature range of −55°C to 105°C, and a capacitance range of 22 μF to 23 μF. AECs are based on the principle of an electrolyte-soaked aluminum oxide dielectric. An electrolyte is an electrically non-conductive liquid, usually an acidic solution, that completes the electrical connection between two metal electrodes. In the case of an AEC, these electrodes are usually formed of aluminum foil, wound together with a separator material, typically paper, plastic, or other non-conductive materials, within a metal or plastic casing. When an electric current is passed through the capacitor, ions from the electrolyte solution are attracted to the electrodes, forming an electric double layer between the electrodes. It is this double layer that stores the electrical charge, or energy, much like a battery. As the charge increases, a significant electric field is created which causes the thickness of the aluminum oxide layer to increase, which further increases the capacitance of the AEC. The ECE-A1VN471UB AEC is designed specifically for high-frequency, high-power DC applications, such as power supplies, audio amplifiers, and voltage regulators. Its ultra-low ESR (Equivalent Series Resistance) and high ripple current capabilities make it ideal for applications where high efficiency and stability are needed. The ECE-A1VN471UB AEC features an extended operating temperature of -55°C to 105°C, a very low equivalent series resistance, and an equivalent series inductance of 0.059 Ω to 0.044 Ω, making it well-suited for high frequency applications. Its maximum ripple current rating is 18.7A, and its life expectancy is 6,000 hours. One particularly beneficial feature of the ECE-A1VN471UB AEC is its ability to operate in extreme temperature conditions. This is a result of its ultra-low ESR and ESI (Equivalent Series Inductance) values, which are both lower than typical capacitors. These features reduce the amount of energy lost in the form of heat, and thus increase the capacitor’s efficiency over a temperature range of –55℃ to 105℃. In summary, the ECE-A1VN471UB AEC is designed for high-frequency, high-power DC applications where stability and efficiency are important. It has an impressive set of features such as low equivalent series resistance, low equivalent series inductance, high ripple current rating and long lifetime, making it a great choice for a wide range of applications.
