Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrical components that provide reliable storage and release of energy for use in a variety of applications. The components consist of two simple parts: an anode, typically made from aluminum foil, and a cathode, usually made from a mixture of paper and electrolyte. The foil and paper pattern is rolled together into a cylinder which is then sealed with an insulating cover. The electric charge is stored between the anode and the cathode, and is released and adjusted when needed.

The UKL2AR47KDD Aluminum Electrolytic Capacitor

The UKL2AR47KDD aluminum electrolytic capacitor is one of the components in a range of reliable high-capacity aluminum electrolytic capacitors. It is a non-polar capacitor with a cylindrical construction, which allows for easy mounting. The capacitor has a voltage rating of 25 volts and a capacitance of 47 µF. It is capable of operating both at higher temperatures, up to 85⁰C, and at lower temperatures, down to -25⁰C, making it suitable for a range of applications.

Applications of UKL2AR47KDD

The UKL2AR47KDD is used in a variety of electroacoustical and electronic systems, including automotive and AC power line circuits, telecommunication equipment and DC/DC converters. It is also found in motor controls, AC filters, and audio amplifiers or PA systems. The robustness and reliability of the UKL2AR47KDD make it suitable for demanding, high-performance systems and it is known for its excellent noise reduction characteristics. Due to its high-stability performance, the capacitor is also ideal for applications where temperature variation has a negative impact.

Working Principle of UKL2AR47KDD

The UKL2AR47KDD is a nonpolar capacitor and operates using a dielectric liquid between the two electrodes. The electrolyte, an ionic liquid, allows for electrolytic conduction between the two electrodes, forming a complete electrical circuit. The capacitor creates a charge separation, storing the electric charge for later use. When a voltage is applied, the current will flow and the capacitor will start to discharge, releasing the stored charge. The rate of discharge depends on the resistance of the circuit and the time it takes for the capacitor to reach its full voltage. The capacitor will then recharge again, and the cycle will repeat itself. The UKL2AR47KDD has a low equivalent series resistance (ESR), which allows it to operate at high frequencies and reduce heat dissipation. This makes it suitable for AC applications at higher temperatures and ensures a higher degree of consistency when compared to other types of capacitor.

Conclusion

The UKL2AR47KDD aluminum electrolytic capacitor is a reliable and robust electrical component that provides efficient and consistent energy storage and release. It is ideal for use in demanding, high-performance applications and provides accuracy and reliability in a variety of electroacoustical and electronic systems. Its low ESR and high temperature operating characteristics enable it to meet the most stringent of requirements, ensuring it remains a popular choice for applications in a variety of industries.
