Aluminum electrolytic capacitors, also called electrolytic capacitors, are polarized electrochemical capacitors with a larger capacitance per volume compared with other types of capacitors, making them useful in applications where relatively large capacitance is required in a limited space. The UVZ1E471MPD is a Non-solid aluminum electrolytic capacitors, which has the advantages of low cost, large capacitance and long life. It is mainly used in high-current, high-stability and filtering applications such as DC-DC power supplies, switching power supplies, motor drivers and audio circuitry. It is also suitable for LED lighting, variable-speed drives, electronic ballasts, industrial automation, etc.

The working principle of an aluminum electrolytic capacitor is based on its construction. An aluminum electrolytic capacitor consists of a sheet of pure aluminum foil, an anodic oxide film formed on the foil and two layers of paper separators soaked in electrolyte. The anodic oxide film acts as the dielectric of the capacitor and increases the capacitance. The electrolyte acts as a conductive medium between the two capacitors and also assists in forming the anodic oxide film. When a voltage is applied across the aluminum capacitor, the aluminum electrode is positively charged and the anode oxide is negatively charged, forming a potential barrier between the two electrodes. This charge balance creates the capacitor effect.

The UVZ1E471MPD is a low Esr model aluminum electrolytic capacitor which has a voltage rating of 63VDC, a capacitance of 470μF and ESR of 1.2mOhms at 100kHz. The ESR (Equivalent Series Resistance) of the capacitor is an important parameter as it defines the equivalent resistance in the capacitor and how effectively it is able to filter or attenuate noise caused by high voltages. This capacitor is suitable for power supply filtering, energy storage applications and power factor correction.

The UVZ1E471MPD is designed with a long life in mind and has a shelf life of up to 10 years in standard storage conditions. It is also designed to resist temperature extremes, with an operating temperature range of -30°C to +85°C and a high temperature of +110°C for up to 1,000 hours. It is also highly resistant to humidity, damp heat, wetting and solder heat, making it ideal for high-precision applications.

The UVZ1E471MPD aluminum electrolytic capacitor is a highly reliable, long-life, high-performance component that can be used in a wide range of applications. It is suitable for use in power supplies, switching power supplies, motor drivers, audio circuitry, LED lighting, variable-speed drives and electronic ballasts, to name a few. Its high capacitance and low ESR make it well-suited for high current and high stability applications.
