Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrical capacitors with a larger capacitance per volume compared to other types. The general construction of an aluminum electrolytic capacitor consists of a metalized electrode films, such as aluminum foil with oxidized aluminum particles, a nonconductive separator (usually glass paper, plastic films, or impregnated paper) saturated in an electrolyte, and aluminum or other metal cans which contains the foil, separator, and electrolyte.

The UUL1H470MNL1GS aluminum electrolytic capacitor is a standard radial leaded device with a capacitance of 470µF and voltage rating of 25V. It is used for power stabilization when the power source voltage is unstable and the storage stability is poor. This capacitor has a low leakage current and a long life, making it an ideal choice for preventing power supply interference in low-power applications.

Working Principle

Aluminum electrolytic capacitors take advantage of the excellent characteristics of aluminum as an electrolyte to form an electrolytic rectifier which stores charge within the device. The negative electrode is generally made of aluminum foil. The positive electrode is composed of an electrolyte which contains positively charged particles in the form of graphite, silver, or soft carbon. When a voltage is applied to the capacitor, the aluminum electrodes form an electric double layer and act as a rectifier. Electric field forces anode and cathode ions to migrate through the electrolyte barrier and be trapped in the form of an electric double layer. This process results in a unit capacitance value, and the capacitance is proportional to the applied voltage.

Application Fields

The UUL1H470MNL1GS aluminum electrolytic capacitor is a reliable device used for a broad range of applications, including automotive, lighting, communication and computing applications. This capacitor is used in the circuits that bridge the high and low loss stages, as well as in power supplies and decoupling circuits to reduce power noise and improve signal-to-noise ratios. This capacitor is also used in the high-frequency band-stop filters, DC-DC converters, high frequency converters, and LED elevators. In addition, the UUL1H470MNL1GS can be used in AC circuits and high-precision instrumentation.

Conclusion

The UUL1H470MNL1GS aluminum electrolytic capacitor is a reliable device with a long life, high linearity and low ESR, making it ideal for high-performance power stabilization and noise-reduction applications. The device has a range of applications in automotive, lighting, computer and communication systems. The device works on the principle of electrolytic rectifier as an electric double layer is formed which stores charge in the device.
