100uF 25V Electrolytic Capacitor

An aluminium electrolytic capacitor, commonly referred to simply as an electrolytic capacitor, uses aluminium metal as one electrode, coated with a very thin layer of aluminium oxide as the dielectric, and an electrolyte as the second electrode. These capacitors are widely used in power supplies and DC-DC converters for smoothing and buffering rectified DC voltages in various electronic devices. Due to their polarization based on the anodization principle, aluminium electrolytic capacitors can only be operated with DC voltage applied with the correct polarity. They are often found in industrial power supplies and have a variety of applications, including input and output decoupling capacitors for smoothing and filtering, DC-link capacitors in AC/AC converters for variable-frequency drives and frequency changers, as well as correction capacitors for power factor correction.
