EEU-EB2C221S

Aluminum electrolytic capacitors, or simply capacitors, are passive electrical components used to store and manage electrical energy through the process of electrostatic charge. By using a wide variety of materials, processes and designs, capacitors can be found in a large number of products and applications. In particular, the EEU-EB2C221S is a type of aluminum electrolytic capacitor manufactured by Panasonic, capable of withstanding temperatures up to 105°C and have a long-term storage temperature of -40 to 85°C. These capacitors are popular in many electronic applications including power supplies, DC-DC converters, audio systems, and more.

The EEU-EB2C221S is a polarized type aluminum electrolytic capacitor, meaning that it must be oriented properly when connected in an application circuit. The cathode is connected to the negative terminal of the capacitor. The cathode also features an internal connection (connected to the negative lead) via the bottom of the capacitor’s terminal. The anode is connected to the positive terminal of the capacitor and the positive lead is typically connected to the application circuit or power supply.

The EEU-EB2C221S contains two leaded metalized aluminum foil electrodes, which are insulatingly mounded via a conductive polymer to form an anode. A dielectric (insulator) is formed by oxidizing the anode with an electrolyte solution, resulting in a thin layer of aluminum oxide. The formed dielectric is porous, allowing for the absorption of electrolyte and thus forming the electrical double-layer structure of the capacitor. This double-layer structure is where the electrical charge is stored, and it is also responsible for the capacitor’s characteristics such as its maximum voltage, capacitance and ESL.

To improve the long-term reliability of the aluminum electrolytic capacitor, Panasonic added a series of additional improvements. A large screw terminal design is used to ensure a secure fit of the capacitor in applications. The capacitor also features a safety valve, which serves to release excess pressure from the internal structure of the capacitor in order to protect the capacitor during temperature fluctuations. It also includes an internal protection circuit, which helps to protect the capacitor from overvoltage and short circuit. Lastly, its housing is plastic supplied rated UL94V-0 for outdoor applications.

The EEU-EB2C221S aluminum electrolytic capacitor is suitable for use in a wide range of applications. Its high capacitance enables it to store a large amount of energy, making it suitable for use in electronic circuits which require higher power storage. Due to its reliability and safety features, it is a popular choice for use in audio systems and power supplies. Finally, its plastic case and UL94V-0 rating make it suitable for outdoor applications. With its wide range of features and applications, the EEU-EB2C221S aluminum electrolytic capacitor is a great solution for your electronic needs.
