Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most common capacitor types in electronics. They are available with a wide variety of physical dimensions and capacities, making them a versatile and affordable way to meet an application’s requirements. The aluminum electrolytic capacitor gets its name from the fact it is made of aluminum and utilizes an electrolytic solution to increase its capacitance. This type of capacitor is best for filtering, buffer, inrush current protection, and energy storage in power supplies.

Application Field and Working Principle

MALREKV05DC122X00K aluminum electrolytic capacitors are used in a variety of applications, including telecom and data processing, audio/video systems, and automotive applications. In these applications, they provide high levels of capacitance and superior filtering, buffering, and inrush current protection. The working principle of the capacitor can be explained in terms of the capacitance created by the plate electrodes. When an alternating voltage is applied across the capacitor, the capacitance will vary with the frequency and level of voltage. The composition and shape of the plates coupled with the type of electrolyte used will determine the capacitance of the capacitor.

Aluminum electrolytic capacitors typically consist of an anode (positively charged plate) and a cathode (negatively charged plate) which are separated by a spacer material. The attached electrolyte connects the electrode plates, forming an electrical bridge between them. The capacitor works by trapping electrical charges of opposite polarity on each of the electrode plates. In order for the capacitor to work, a voltage difference must be applied across the plates, creating an electrostatic field which attracts free electrons to fill the depleted charges on the opposite electrode and thereby creating static-potential energy within the capacitor. As the voltage across the capacitor changes, the electrostatic field between the plates will strengthen or weaken, thereby increasing or decreasing the capacitance.
