Aluminum electrolytic capacitors are widely used components in electronic and electrical systems. Typically consisting of two aluminum foils separated by a paper or plastic dielectric, they serve to store energy, filter signals, and as building blocks for other circuit elements. The UUE1C471MNS1ZD is a snap-in style, 450V, 47uF aluminum electrolytic capacitor made by Nichicon Manufacturing Services in Japan.

Application Fields

Capacitors are widely used in a multitude of applications. Their direct or indirect roles commonly include regulating voltage and current; storing energy; controlling inductors; and filtering, stabilizing, shaping, and coupling signals. Because aluminum electrolytic capacitors feature a very low ESR (equivalent series resistance) and ESL (equivalent series inductance), they tend to be preferred in power-supply circuits, telecommunications, consumer electronics, motors, and automotive applications.

The UUE1C471MNS1ZD capacitor is most suitable for circuit installations, where its snap-in capability improves fastening times, as well as provides easy mounting, removal, and replacement. Its remarkably low ESR range and wide temperature range of -55°C to +85°C make it suitable for both industrial and commercial applications.

Working Principle

The UUE1C471MNS1ZD is an aluminum electrolytic capacitor specifically designed to meet the requirements of devices such as switchgear, motor drives, UPS systems, industrial inverters, etc… The fundamental principal behind the operation of electrolytic capacitors is the electro-chemical reaction between the aluminum plates and the electrolyte (a liquid or paste). In a typical design, one of the plates is coated in a thin layer of non-conductive oxide which is formed as a result of the electro-chemical reaction between the electrolyte and the aluminum.

The oxide layer acts as an insulator and prohibits electrical current from flowing between the two plates. The other plate is usually in the form of a thin strip of aluminum with an electrically conductive coating. When a voltage is applied across the capacitor, the electrical charge on the metallic layer attracts the ions from the electrolyte, thus producing the electric field required for storing energy.

The primary energy-storing capacity of the UUE1C471MNS1ZD is 47uF, meaning that the capacitor can store and release an electrical charge of 47icrofarads (47 UF). Its high ripple current rating also makes it suitable for use in regulated DC power supplies, as well as in applications such as computers and consumer electronics. The device also features an extremely low ESR (equivalent series resistance) of 35mΩ (Max.) at 1kHz.

Conclusion

The UUE1C471MNS1ZD aluminum electrolytic capacitor is a robust, reliable, and cost-effective way to store electrical energy, filter signals, and as building blocks for other circuit elements. Its combination of robust snap-in mounting, wide temperature range, low ESR, and high ripple current make it an ideal choice for a multitude of applications in power-supply circuits, telecommunications, consumer electronics, motors, switchgear, UPS systems, industrial inverters, and more.
