120uF 450V Electrolytic Capacitor

120uF 450V Electrolytic Capacitor

The 120µF 450V Electrolytic Capacitor is a high-voltage, high-reliability aluminum electrolytic capacitor designed for demanding power electronics. With a capacitance of 120 microfarads and a 450-volt rating, it is ideal for circuits connected directly to rectified AC mains, such as SMPS primary stages, inverters, PFC circuits, and high-voltage power supplies.

Built with rugged aluminum foil, high-quality electrolyte, and low-ESR construction, this capacitor offers excellent ripple current handling, stable performance under high voltage stress, and long service life in continuous-duty environments. Its cylindrical radial design ensures secure PCB mounting and compatibility with industrial, commercial, and consumer power systems.

This capacitor is suitable for bulk energy storage, DC bus stabilization, and noise suppression in high-voltage applications, making it a reliable component for both new designs and power equipment repair.
