Aluminum electrolytic capacitors, often referred to as electrolytic caps, are polarized capacitors whose anode electrode consists of a layer of pure aluminum, which acts as the working electrode. The oxide layer on the aluminum anode forms a dielectric which is interrupted by a thin organic barrier film to prevent the electrolyte from passing directly into the anode material. The dielectric layer is formed in a liquid solution, or in an electrolyte rich in protons. The cathode electrode is composed of an electrolyte and a metal (usually nickel) grid. An external voltage is applied to the capacitor, causing an electrical current to flow from the anode to the cathode.

The EDH337M063S9TAA capacitor is a high ripple current aluminum electrolytic capacitor. It is a long life, low impedance capacitor with a voltage rating of 63VDC and a capacitance of 337μF. The EDH337M063S9TAA is designed for automotive applications, such as Electronic Control Units (ECUs) and other power electronic systems. Its compact size and low impedance make it ideal for high frequency applications such as switching power supplies, and other automotive applications.

The EDH337M063S9TAA is designed to handle high ripple currents, with its rated ripple current nearly doubling the maximum ripple current of industry standard aluminum electrolytic capacitors. This allows for better power delivery and higher efficiency in applications where high current is required. Additionally, the EDH337M063S9TAA\'s low ESR and ESL ensure its reliability for high ripple current operation and high reliability in automotive applications.

The aluminum electrolytic capacitor utilizes the Faraday effect to store charge. The capacitance of the capacitor is determined by the area of the electrodes, the distance between the electrodes, and the dielectric strength of the electrolyte. A high voltage is applied to the capacitor to cause a current to flow through the dielectric, forming an electric field. This field polarizes the electrolyte ions and develops a counter-electric field. The effect of these electric fields is to store a charge for a certain period of time. The amount of charge stored is proportional to the applied voltage and is determined by the size of the capacitor.

The EDH337M063S9TAA is a long-life, low-impedance aluminum electrolytic capacitor designed for automotive applications. Its very low ESR and ESL values ensure high reliability for high ripple current operation and long-term reliability for automotive applications. Its high capacitance and voltage rating make it ideal for applications that require high current delivery and efficiency, such as Electronic Control Units (ECUs) and other power electronic systems. Furthermore, its small size and compact design makes it suitable for high frequency applications where space is limited.
