Aluminum electrolytic capacitors are an electronic component that stores electrical energy, just like a rechargeable battery. The primary application field of EEU-FC0J821LB is in transient energy storage and frequency selection applications.

The structure of an EEU-FC0J821LB capacitor consists of a pair of aluminum foils wound in a spiral, alternating with a paper isolator that serves to insulate the two leads. A thin layer of electrolyte on the surfaces of the aluminum foils serves to act as a filter and increase their conductivity. The two ends of the capacitor are sealed with a dielectric material, such as epoxy resin, to protect the internal electrical components from dust, moisture, and other environmental contaminants.

When an electric potential is applied across the terminals of the EEU-FC0J821LB, an electric field is induced between the outer and inner electrodes. This electric field produces an electrochemical reaction between the aluminum and the electrolyte which generates a current flow through the electrodes. This current establishes an oxide layer on the aluminum surfaces and the stored electric charge remains stored until the applied voltage is removed.

The working principle of the EEU-FC0J821LB capacitor is based on Faraday\'s Law of Electrolytic Capacitance. This law states that the capacitance of a capacitor is directly proportional to the ratio of the surface area of the electrodes to the distance between them. This means that the higher the ratio of the surface area to the distance between the electrodes, the higher the capacitance of the capacitor. In addition, the capacitance of the capacitor can also be increased by decreasing the thickness of the oxide layer on the aluminum surfaces.

The EEU-FC0J821LB capacitor is widely used in high frequency applications such as RF receivers, transmitters, and amplifiers. It is also used in industrial and automotive electronics and other applications where a reliable energy storage mechanism is required. Its primary application field is in transient energy storage and frequency selection applications. It is also used in both low frequency and high frequency low power applications, as well as in high voltage power supply applications.

The EEU-FC0J821LB capacitor is a reliable and cost effective form of energy storage, and its applications in frequency selection are becoming increasingly popular. The combination of its high capacitance, low equivalent series resistance and long life make it an ideal choice for a variety of applications.
