An axial leaded aluminum electrolytic capacitor is a type of capacitor with leads (electrical conductors) that exit from opposite ends of its cylindrical body, projecting in a straight line. It utilizes a wound roll of aluminum foil and an electrolyte-soaked spacer paper to store electrical energy, making it suitable for high-current, high-reliability applications. The axial lead design allows for low-profile mounting in electronic circuits, though radial-lead capacitors offer a smaller board footprint by mounting vertically.
Applications:
These capacitors are often used in demanding industrial and commercial applications where their high reliability, long life, and robust construction are beneficial.
