Aluminum electrolytic capacitors use a thin layer of oxide that separates two metal plates (an anode and a cathode) within a cylindrical or rectangular casing. They are a type of passive electrical component and can store electrical energy temporarily. Aluminum electrolytic capacitors are most commonly used in power management and supply systems due to their very high capacitance for a given size, as well as their strong resistance to current leakage. They are also often used in low-frequency electrical circuits and high-frequency electronic applications due to their excellent frequency response and stable capacitance over temperature.

The EET-UQ2G681KA aluminum electrolytic capacitor is a radial-leaded component with a rated voltage of 6.3 volts and an operating temperature range from -55 to +105 °C. It has a maximum ripple current capability of 0.54A and a low ESR of 2.5 Ohms. The EET-UQ2G681KA also has a very good tolerance rate of ±20%. It is a general purpose, higher temperature aluminum electrolytic capacitor, often used in applications such as power supplies, amplifiers, and computers.

The EET-UQ2G681KA operates on the principle of Faraday’s Law of electrolysis. Hydrogen gas is formed on the anode due to the electrolysis between the anode and the electrolyte as a reaction of current movement. This gas is very soluble in the electrolyte and it is usually separated by a thin porous oxide layer that maintains a minimum gas pressure inside the capacitor. The resulting high dielectric constant between the metal plates provides a high capacitance.

In addition, the EET-UQ2G681KA offers low ESR, good current leakage characteristics, vibration resistance, low cost, and low physical volume due to the compact design of the capacitor. Furthermore, they offer an extended operating temperature range, and their electrical and environmental performance over time is reliable and consistent with minimal self-discharge.

Aluminum electrolytic capacitors like the EET-UQ2G681KA are widely used in a variety of power supply and energy storage applications, such as dc-dc converters, filter capacitors, and surge suppressors. In addition, they can provide reliable support in energy recovery and voltage regulation, power smoothing circuits, and other high frequency applications. Furthermore, the extended capacitor life and reliable performance over time make them the ideal choice for applications in which major power outages would be unacceptably costly.

In summary, the EET-UQ2G681KA aluminum electrolytic capacitor is a compact, reliable, and cost-effective solution for power management and supply in a wide range of applications. The capacitor provides low ESR, excellent tolerance rate, and extended operating temperature range, making it a great choice for high frequency and general purpose applications.
