Aluminum Electrolytic Capacitors

An Aluminum Electrolytic Capacitor (AEC) is a type of capacitor characterized by its high capacitance and quick self-charging behavior. It is an energy storage device used to store electrical energy and then release it quickly when needed. AECs are extensively used in power supplies, motors, and other high frequency circuits, where it needs to store a large amount of energy in a small package, and quickly release it when needed. The main components of an AEC include a metal-oxide-film capacitor, a dielectric electrolyte, and an anode formed by aluminum.

ESMG101ELL221MK25S Application Field and Working Principle

The ESMG101ELL221MK25S aluminum electrolytic capacitor is a type of radial-lead capacitor, which is used in a wide variety of applications. It has a capacitance of 5.8mF, and its maximum voltage rating is 450VDC, with a maximum ripple current of 1.0A rms. It has a lead spacing of 10mm, and its rated temperature range is -55 to +125 degrees Celsius. The ESMG101ELL221MK25S has excellent reliability and low impedance characteristics, making it a suitable choice for high frequency power supplies, voltage converters, switch mode rectifiers, and industrial inverters.

The working principle of an aluminum electrolytic capacitor is based on Faraday’s law of electrolysis. When an electric field is applied across the capacitor, the oxide layer on one side of the aluminum reacts with the electrolyte, causing a space charge to form. This space charge creates an area in which charges can move freely. When a voltage is applied to the capacitor, the electric field will cause electrons to move through the oxide layer to the anode, thus creating a current flow through the electrolyte. This current flow, in turn, creates an electric field, which acts as a constant charging force on the capacitor. As the capacitor charges, the internal resistance of the capacitor increases, decreasing the current flow and thus allowing the capacitor to hold a steady voltage.

The ESMG101ELL221MK25S is an excellent choice for applications that require a reliable capacitor with high capacitance and fast charge and discharge characteristics. It is suitable for use in high frequency switching/switching rectifiers, voltage converters, and other applications that require a strong, reliable capacitor.
