Aluminum electrolytic capacitors, commonly referred to as "electrolytics", are a type of electrical component which uses a pair of conductive aluminum foils and a conductive oxide layer to store electrical energy. The aluminum electrolytic capacitor is polarized by nature and thus requires a certain orientation during installation.

The EEU-EB1V102B is a radial leaded aluminum electrolytic capacitor. It has a rated voltage of 100Vdc and a capacitance of 1µF. It is characterized by its low ESR (equivalent series resistance) and low equivalent series inductance (ESL), making it suitable for applications such as high frequency, high ripple current circuits. The EEU-EB1V102B also offers a wide temperature range, from -55°C to +105°C.

The primary application of the EEU-EB1V102B is decoupling. They are used to filter out interference and noise between two components or circuits. When connected between the two components, the capacitor acts as an energy reservoir, storing energy from one source and releasing it to another. This ensures a steady transfer of energy and prevents interference in the circuit.

The working principle of the EEU-EB1V102B is simple. It consists of two aluminum plates, separated by a dielectric layer of aluminum oxide. The plates are polarized with a positive plate and a ground plate. When a direct current is applied to the capacitor, the positive plate gains an electric charge, while the ground plate remains neutral. This creates a potential difference between the two plates, which leads to the creation of a voltage drop across the capacitor. This voltage drop is then used to store energy in the form of a capacitance. As the current passes through the capacitor, charge is transferred between the two plates until the potential difference between them is equalized.

Another interesting feature of the EEU-EB1V102B is its operating life. It has a service life of 3000 hours at 105°C, and 10000 at 85°C. This is due to its small ESR, which helps keep the temperature inside the capacitor low. The relatively low dissipation factor of the capacitor helps prevent self-heating, further extending its lifespan.

In summary, the EEU-EB1V102B is an excellent choice for high frequency, high ripple current applications. Its wide temperature range, low ESR and ESL, and long operating life make it a great option for any circuit. Its primary application is decoupling, where it can provide effective energy storage and smooth transfer of power between components.
