Aluminum Electrolytic Capacitors are devices that are used to store electrical energy and to provide various electrical treatments. In particular, they are used to smooth out the irregularities of electric current, to reduce the effects of electric shock, and to boost the uniformity of electric signals. The EEU-FS1C821 is an example of one such device.

The EEU-FS1C821 is a medium-sized, sealed aluminum electrolytic capacitor. It has a cylindrical aluminum can and two lead terminals that are turned outward. It is particularly suitable for use in acoustics, electron equipment, and power supplies. This device is designed to provide high-performance filtering, ripple control, and surge suppression in such applications.

The working principle of the EEU-FS1C821 is based on the phenomenon known as “double layer capacitance.” Double layer capacitance is the ability of an electrolyte to store electrical energy in two different dielectric layers. In an aluminum electrolytic capacitor, the two layers are the electrolyte and the metal capacitor plate, which is situated between the two. The electrolyte material is typically a solution of an electrolyte such as ethylene glycol or sodium hydroxide. The metal plate is typically made of aluminum and is mounted on an insulating substrate.

When a voltage is applied across a capacitor, an electrical current flows between the two electrodes. The electrical current interacts with the electrolyte and creates a separation of charge across the two dielectric layers. This separation of charge stores energy in the form of an electric field. The electric field generated then creates an electrical capacitance. Therefore, the capacitance of an aluminum electrolytic capacitor is determined primarily by the size and shape of its metal plate, as well as the dielectric constant of the electrolyte used.

The EEU-FS1C821 capacitor has an electrostatic capacitance range of 0.047uF - 470uF and is rated for a temperature range of -55 degrees C to 125 degrees C. It also has an impedance rating of 1kHz and a voltage rating of 350vDC. Furthermore, the EEU-FS1C821 capacitor is RoHS compliant.

In summary, the EEU-FS1C821 is a type of aluminum electrolytic capacitor that is used in applications such as acoustics, electron equipment, and power supplies. It utilizes the phenomenon of double layer capacitance to store electrical energy and provides high-performance filtering, ripple control, and surge suppression capabilities. Its rated capacity, temperature range, and voltage rating make it suitable for a wide range of applications.
