680uF 400V Electrolytic Capacitor

680uF 400V Electrolytic Capacitor 

The 680uF 400V Electrolytic Capacitor is a high-quality aluminum capacitor designed for medium to high-voltage power supply applications. It provides excellent energy storage, voltage smoothing, and ripple filtering, making it well-suited for SMPS power supplies, AC–DC rectifier circuits, inverter modules, UPS systems, and high-power audio amplifiers.

With a 400V rating, this capacitor is ideal for circuits that operate from rectified AC mains (typically around 300V DC). The 680uF capacitance ensures stable DC output even during heavy load changes, while its low ESR design improves efficiency and enhances performance in high-frequency switching circuits. The rugged aluminum can construction ensures long service life, good thermal stability, and consistent performance in demanding industrial environments.
