Aluminum electrolytic capacitors are a type of electrolytic capacitor that uses aluminum foil as an anode separated from a cathode by an electrolyte. A UPB1C471MPD is an aluminum electrolytic capacitor specifically designed for automotive use. It has the advantages of high/low temperature performance, long life, and good resistance to vibration and shock.

The main application field of the UPB1C471MPD is for the voltage stabilization of the automotive power system. This component can be used to reduce the voltage fluctuations of the system, which can contribute to the smooth operation of the vehicle. The UPB1C471MPD can also be used for signal filtering, frequency conversion, noise control, frequency modulation, and other applications.

To understand the working principle of the UPB1C471MPD, we need to look at how its components – the anode, cathode, and electrolyte – interact. When a voltage is applied to the capacitor, the anode produces an oxide layer due to the electrolyte. This layer acts as an insulator, preventing current from flowing between the anode and cathode. As the capacitor builds up charge, the voltage across the capacitor increases, compressing the oxide layer. Eventually, when the charge is removed, the oxide layer returns to its original thickness.

The UPB1C471MPD is designed to handle a wide range of temperatures, from -40°C to +125°C, and delivers excellent performance in extreme conditions. Its internal design offers improved axial and radial strength, with vibration resistance up to 500 m/s2 at 10-2000 Hz. This improves durability and increases its operational life. The UPB1C471MPD also has reliable leakage performance, with a maximum allowe leakage current of 1.0 μA at 125°C.

Aluminum electrolytic capacitors, including the UPB1C471MPD, are integral components of many automotive systems. They are ideal for voltage stabilization, signal filtering, noise control, frequency conversion, and other applications. The UPB1C471MPD is designed to provide superior performance and reliability even in extreme conditions, making it an ideal choice for automotive use.
