Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized capacitors in which the anode is an aluminum foil that is covered on both sides with an electrically conductive material. In the EEE-FC1V221AP application field, the use of aluminum electrolytic capacitors is widely employed, primarily due to its ability to store large amounts of energy and its affordability despite its lack of reliability.

The EEE-FC1V221AP capacitor is a highly tolerant, long-life, non-solid aluminum electrolytic capacitor. It is rated to have a maximum capacitance value of 220µF, a working voltage of 16Vdc and a maximum ripple current of 2.6A. Additionally, its temperature grade rating is 85°C, making it suitable for a wide range of applications.

Working Principles of the EEE-FC1V221AP

The working principle of an aluminum electrolytic capacitor is based on the Faraday principle that states that charge accumulates on an electrode when an electric current passes through an electrolyte. This principle was first proven by Michael Faraday during the 1800\'s and it is still used today in the operation of aluminum electrolytic capacitors.

In the EEE-FC1V221AP, the aluminum electrode is electroplated and the electrolyte is made of a special material that is activated for selective ion diffusion. This process forms a dynamic semiconductor layer by electronic absorption of ions, forming a dielectric layer. As an electric current passes through this layer, a voltage is induced across the capacitor and charge accumulates. This charge is proportional to the current passing through the capacitor, and the total amount of charge stored is proportional to the area of the electrodes.

When the capacitor is used in DC applications, a small leakage current still passes through the capacitor due to the presence of ions in the electrolyte. This leakage current is usually in the order of a few microamps and it is dependent on the working voltage and temperature. The leakage current increases with the working voltage, so it is necessary to choose the appropriate design in order to reduce this current.

Applications of the EEE-FC1V221AP

The EEE-FC1V221AP can be used in a wide range of applications, such as general-purpose power supply circuits, power line filter circuits, DC-DC converters and other power supplies, decoupling and energy storage applications, and any high-frequency circuit that requires a large capacitive load. Furthermore, the capacitor is compatible with standard surface mount soldering techniques, and can be used in all types of printed circuit boards where a long-term, stable electrolytic capacitor is required.

Due to their high capacitance and low cost, aluminum electrolytic capacitors are widely used in electronic equipment, such as power supplies, microprocessors, controllers, audio amplifiers, measuring instruments, and machine tools. The EEE-FC1V221AP is an ideal choice for these kinds of applications as it provides a long-life, highly reliable, and cost-effective capacitor solution.
