Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors are a type of capacitor that uses an oxidized aluminum to act as an electrolyte to store electric energy. The most common types of these capacitors are electrostatically charged with energy, so they can be used to filter out alternating current (AC) or to store energy for pulsed power supply applications. The ELXS451VSN271MQ50S is an aluminum electrolytic capacitor typically used in consumer electronics, personal computers, and power supply products.

Application Field

The ELXS451VSN271MQ50S capacitor is part of the voltage-oriented series of aluminum electrolytic capacitors and provides a nominal capacitance of 270μF with a rated voltage of 450VDC. The ELXS451VSN271MQ50S is typically used in applications requiring a high capacitance and high voltage rating such as power supplies, motor drives, battery back-up circuits, UPS systems, display controls, pulse control circuits, and LED lighting.

Working Principle

The working principle of aluminum electrolytic capacitors is based on the use of an anode, a cathode, and a medium called an electrolyte. The anode is made of highly active, pure aluminum foil. The aluminum foil is then processed and chemically treated to form a very thin oxide layer. The oxide layer acts as the dielectric material between the anode and the cathode, and provides insulating properties. The electrolyte is then inserted between the anode and the cathode to allow for charge exchange. When connected to a source of voltage, the electric field generated between the anode and the cathode causes electric charge to pass through the oxide layer, storing energy.

When a reverse voltage is applied, the electric field is opposed and the stored electric charge can be released again. This is the basic working principle of an aluminium electrolytic capacitor. As such, it is used to provide good filtering of AC current and DC current and can be found in a wide variety of consumer electronics.
