EEU-FC2A471

Aluminum electrolytic capacitors are non-polarized capacitors consisting of an aluminum foil, steel mandrel and a special anode. The high temperature anode is formed from anodized aluminum and its corresponding electrolyte, and the anodization process results in an anode with greatly increased surface area. This improved surface area provides increases in capacity. The anode is connected to the steel mandrel, which prevents the anode from being damaged or warped. A dielectric layer of aluminum oxide forms between the steel mandrel and the anode, allowing the current to pass between the anode and the steel mandrel.

The main purpose of aluminum electrolytic capacitors is energy storage. They are used as part of electrical circuits to filter out ripple and noise, store energy to provide a steady current, provide protection to electrical components, and reduce harmonic distortion. In addition, they are also used in filtering, timing, and de-coupling applications.

EEU-FC2A471 Application Field and Working Principle

The EEU-FC2A471 is a high ripple current, snap-in style aluminum electrolytic capacitor. It features a capacitance range from 2.2μF to 470μF and a rated voltage of 400V. This capacitor is ideal for applications that require long life and low impedance. Its snap-in feature allows for easy installation into any PCB.

The working principle of the EEU-FC2A471 is based on Faraday’s law of electrolysis. When a voltage is applied to the capacitor, a reaction occurs between the electrolyte and the aluminum foil. The aluminum foil forms an anode and the current will pass through the electrolyte. This causes the creation of a layer of anodic oxide on the aluminum foil, which acts as a dielectric layer between the anode and the steel mandrel. This allows for a current to pass, which in turn causes the capacitance of the capacitor to increase.

The EEU-FC2A471 capacitor is commonly used in switching power supplies and DC-DC converters. It is also used in motor drives, DC-AC inverters, and AC adapter circuits. Additionally, it can be used in power conversion circuits, energy storage applications, and any other application that requires high ripple current, long life, and low impedance.
