Aluminum electrolytic capacitors are a type of capacitor that utilizes the electrolytic oxidation process for two dissimilar metals to form a layer of oxide locally on the surface, which acts as a dielectric material. The EEU-FR1E821 is an aluminum electrolytic capacitor designed to offer a large capacitance value in a much smaller package compared to other types, allowing it to be used in a variety of applications.

The EEU-FR1E821 is a radial lead type capacitor, meaning the leads are connected directly to the sides of the capacitor. It is constructed using aluminum oxide and aluminum as the dielectric and electrodes, respectively, as well as electrolytic solvent for insulation. Its temperature rating is 85 °C, and it features a capacitance of 1,000 pF with a voltage rating of 250 V, making it suitable for an array of circuits from audio to lighting.

Its metalized aluminum can is the defining feature between the EEU-FR1E821 and other types of capacitors. These metalized can designs prevent the formation of dendrites and provide superior heat dissipation, both of which aid in increasing energy density and electrical performance. Additionally, the metalized can increases the operating temperature range of the capacitor and reduces the risk of contamination when working in harsh environments.

The general principle of working in an aluminum electrolytic capacitor is similar to other types of capacitors, but with the additional feature of voltage balancing. The voltage balancer quickly charges the capacitor upon the application of an external voltage, resulting in an even distribution of the voltage across the plates. This creates a higher dielectric strength than other capacitors, meaning it can store more charge.

The EEU-FR1E821 is an ideal choice for a variety of applications which require a compact and reliable solution to store a sizeable amount of charge. These applications include power supplies, audio systems, and higher power LED lighting. It is also used as a buffering and decoupling capacitor for output stages, where its ability to withstand a higher voltage is vital for performance and safety hazard prevention.

In summary, the EEU-FR1E821 is a radial lead type aluminum electrolytic capacitor that offers a high capacitance value in a much smaller package compared to other types. It is constructed using aluminum oxide and aluminum as the dielectric and electrodes, respectively, along with electrolytic solvent for insulation. Its temperature rating is 85°C and it features a capacitance of 1,000 pF at 250 V, making it suitable for a number of audio, lighting and buffering/decoupling applications. Furthermore, the metalized aluminum can provides superior heat dissipation and increased energy density, resulting in better electrical performance and longer life for its users.
