Aluminum Electrolytic Capacitors: EKZH350ELL470ME111 Application Field and Working Principle

Aluminum electrolytic capacitors (also known as electrolytic capacitors) use aluminum oxides, sheets of aluminum foil, and electrolyte liquid to provide the electric field needed for the capacitor to function. They provide very large capacitance values for their physical size compared to other types of capacitors, and are therefore often used in computer circuits, audio systems, signal-filtering, and communications systems.The EKZH350ELL470ME111 is a popular choice of aluminum electrolytic capacitor because it offers high voltage and long life. It is a non-polarized electrolytic capacitor that has a current capacity of 350 VDC and a low equivalent series resistance (ESR). It is primarily used in audio systems and precision functions, helping to ensure consistent and reliable performance in noisy and challenging environments.The EKZH350ELL470ME111 is constructed from two rolls of aluminum foil – one mounted on the outside and another on the inside. The aluminum foil is interleaved with a layer of insulating material, and the two foil rolls are placed inside of an electrolyte-filled can. The can acts as the housing for the capacitor.When the capacitor is being used, a voltage bias is applied to the two poles of the capacitor. As the bias voltage increases the capacitance of the capacitor reduces due to the charges in the aluminum oxide layer. Conversely, the capacitance increases when the bias voltage decreases. As a result, the capacitor can be used to filter out high-frequency noise or to reduce voltage fluctuations in sensitive circuits.The working principle behind the EKZH350ELL470ME111 is simple yet effective. It utilizes an oxide layer between the two aluminum foils that is immersed in an electrolyte. This oxide layer is charged when a voltage bias is applied, and it is discharged when the bias voltage reverses. As the capacitor is charged and discharged, the aluminum foils pass current through the oxide layer to charge and discharge the capacitor.The EKZH350ELL470ME111 aluminum electrolytic capacitor is a reliable and long-lasting capacitor that is ideal for applications such as audio systems, signal-filtering, and communications systems. Its electrolyte-filled can housing provides robust protection for the capacitor’s components, and its low equivalent series resistance, long life, and high voltage outputs make it suited for precision functions.
