Aluminum electrolytic capacitors are electrochemical capacitors with enhanced capacitance values. They use the phenomenon of reversibly stored charge at the surface of aluminum oxide film to provide excellent capacitance values in tiny footprints.

The UVY1C471MPD aluminum electrolytic capacitor is an omnidirectional polarized device designed for use in rectified circuits. It is a non-polar device rated at 4.7V and is capable of tolerating DC reverse voltage up to 10V. The capacitance value is 47uF, and the package is maximum 25.4mm in diameter.

The lifetime of this aluminum electrolytic capacitor is in excess of 2000 hours at its rated voltage and at its rated temperature (105°C). The maximum tanδ of this component is 0.25 at 120Hz and 25°C.

In terms of working principle, aluminum electrolytic capacitors use electrolysis of aluminum oxide, resulting in an electrically insulating layer separated from the body of the aluminum by an electrolyte. The result of this process is surface charge, which is what allows the capacitor to store electrical energy. The nature of the electrolyte and the thickness of the insulating layer are key features of the aluminum electrolytic capacitor, and they determine the capacitance value, leakage current, and voltage. When reverse-biased, the electrolyte behaves as an additional insulator and prevents leakage current.

The UVY1C471MPD aluminum electrolytic capacitor is particularly suitable for use in applications such as motor control, telecommunication, energy conversion, and power systems. In motor control applications, the capacitor is used to absorb pulses and spikes during starter operations. It is also capable of providing surge current for the motor. In telecommunication applications, the capacitor is used to maintain a constant supply voltage for sensitive communication components. As for energy conversion and power systems, the capacitor helps to perform the filter function and reduce high-frequency noise.

In conclusion, the UVY1C471MPD aluminum electrolytic capacitor is a highly reliable and cost-efficient option for critical applications which require high capacitance values and excellent reverse-biased tolerance. It is capable of providing surge current for motors and maintaining a constant supply voltage for sensitive communication components, thus making it an ideal choice for these areas of application. Furthermore, its lifetime is in excess of 2000 hours and its maximum tanδ is 0.25 at 120Hz and 25°C.
