Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors have become increasingly popular among engineers and professionals due to their superior performance and long lifetime reliability. An aluminum electrolytic capacitor, such as the UKT1A471MPD, is an ideal choice for use in high-voltage direct current (HVDC) applications. This type of capacitor is an effective solution for a wide variety of projects, including power conditioning circuits, frequency convergence filters, and audio crossover networks.

What is an Aluminum Electrolytic Capacitor?

An aluminum electrolytic capacitor is a polarized capacitance device that consists of two metal foils (anode and cathode) that are coated by an electrolytic metal oxide layer. These capacitors are able to store electrical energy and can be used in alternating current (AC) or direct current (DC) applications. The metal foils are wound around a spindle and insulated with a separator. This design creates a cylindrical container with a cathode on the outer surface, anode at the center, and electrolytic metal oxide layer that covers the whole surface of the capacitor.

The UKT1A471MPD

The UKT1A471MPD is a widely used aluminum electrolytic capacitor. It is especially suitable for high voltage direct current (HVDC) applications. Typically, the UKT1A471MPD is used in power conditioning circuits, frequency convergence filters, and audio crossover networks.The UKT1A471MPD is a polarized capacitor with a maximum working voltage of up to 250V, and has a capacitance of 1uF. It has a low temperature coefficient, which helps ensure maximum temperature stability and decreased risk of failure. Additionally, this type of capacitor has a lifetime longevity up to 2000 hours of use at its nominal voltage, making it a reliable and cost-effective choice for many projects.

Working Principle

The UKT1A471MPD capacitor works according to the principle of a dielectric material. This material is composed of two metallic electrodes that are separated by an insulating layer. When an electric field is applied to the electrodes, the electric field causes a displacement of charges, which creates an electric current. The electrons move between the two electrodes, resulting in a charge imbalance over the dielectric layer. This charge imbalance creates an electric field within the dielectric material, which stores energy in the capacitor.When the applied voltage is removed, the capacitor slowly discharges, releasing the stored energy. This discharge creates an electric current, which reduces the charge imbalance over the dielectric material and eventually restores the potential difference between the two electrodes.

Conclusion

The UKT1A471MPD is an ideal choice for use in high-voltage direct current (HVDC) applications. Its superior performance and long lifetime reliability make it a cost-effective and reliable solution for a wide range of projects. Its working principle is based on a dielectric material composed of two metallic electrodes that are separated by an insulating layer. When an electric field is applied, the electric field causes a displacement of charges which creates an electric current. When the applied voltage is removed, the capacitor slowly discharges, releasing the stored energy.
