Aluminum Electrolytic Capacitors - MAL211947331E3 Application Field and Working Principle

Aluminum electrolytic capacitors, commonly known as "aluminum caps" or "electros" for short, are a form of electrolytic capacitor. The terminals of aluminum electrolytic capacitors are made from aluminum foil, and the dielectric layer is formed by a layer of oxide film formed on the surface of the aluminum foil submerged in the electrolyte medium. This type of capacitor has the characteristics of high capacitance, small size, long life, and is widely used in the electronics industry as a general-purpose storage electronic component.

MAL211947331E3 aluminum electrolytic capacitor is a low impedance, snap-in type aluminum electrolytic capacitor that is suitable for voltage ratings of 16V or higher. It is used to reduce AC or DC voltage fluctuations, high frequency noise, power supply ripple, over-voltage etc. This capacitor is suitable for use in switch mode power supplies, frequency converters, ballasts, lighting, and various types of motors.

Working Principle of MAL211947331E3

The MAL211947331E3 aluminum electrolytic capacitor is constructed with two aluminum foils that are etched specifically to increase the surface area. A layer of oxide is then formed on the surface of the aluminum foils, immersion in an electrolyte medium, and sealed into a hermetically sealed can. This forms an electric double layer capacitor.

When a voltage is applied across the capacitor, electrons flow from the anode (positive electrode) to the cathode (negative electrode) through the oxide layer. The flow of electrons causes a current to flow and this current will charge or discharge the capacitor, depending on the direction of the current. This charge or discharge of the capacitor creates a build-up of opposite electrical charges on both sides of the capacitor, which is the primary principle of operation for aluminum electrolytic capacitors.
