Aluminum electrolytic capacitors are electrochemical capacitors which use an aluminum oxide as the dielectric material and the oxide layer as the capacitance. They can be very small and their capacitance can vary from a few microfarads to a few thousand microfarads, making them more attractive than other capacitor types. The UVP1H101MPD1TD is an aluminum electrolytic capacitor by Nichicon and is widely used in a variety of applications.

This UVP1H101MPD1TD aluminum electrolytic capacitor is suited for use in a wide range of applications. It can be found in analog circuits, audio equipment, information-processing equipment, automotive applications, consumer electronics, as well as metering and communication equipment. It can also be used in DC-DC converters, voltage duplicators, and switching regulators. The device offers stable circuit operation and performance at temperatures between -40°C to 85°C, and has the ability to withstand frequent transportation conditions and high temperature storage.

The UVP1H101MPD1TD works on the principle of an aluminum foil and the electrolyte replacing paper as the dielectric in a conventional capacitor. This series uses a cathode aluminum foil that is etched to form a number of fine parallel grooves, immersed in electrolyte which is separated from the anodic aluminum foil by a paper separator. This arrangement allows for a large capacitance due to the high capacitance of the electrolyte.The anodic oxide film formed on the anodic aluminum foil acts as an insulator and prevents any current from flowing. The application of an AC or DC voltage between the two aluminum foils creates a charge in the electrolyte which results in an electric field between the two sides. This electric field results in the electrolyte molecules becoming polarized, forming a dielectric layer between the two aluminum foils.

The polarization of the molecules forms a capacitance in the form of an electric energy storage device. Due to the presence of the electrolyte, the capacitance of the capacitor is large and the inter-electrode distance is shorter than that of the conventional capacitor. As the capacitance increases, so does the amount of charge that can be stored and, hence, the potential number of applications.

These UVP1H101MPD1TD aluminum electrolytic capacitors provide excellent performance in demanding applications and are ideal for dealing with high currents and low frequencies. With their wide temperature range, high capacitance values, and excellent reliability, they are a popular choice for many applications.
