120uF 450V LEAD Electrolytic Rubycon Capacitor 120uF 450V

Product Overview

The Rubycon 120µF 450V electrolytic capacitor is a premium, high-voltage, polarized radial through-hole (leaded) component. Manufactured by Rubycon—a tier-one Japanese manufacturer renowned for exceptional reliability and longevity—this component is engineered for primary-side AC mains rectification, bulk energy storage, and Power Factor Correction (PFC) filtering in high-demand power systems.

A 450V rating provides the essential safety headroom required to handle the high DC bus voltages (typically 310V to 380V DC) generated by rectified 220V/240V AC mains. It is a critical component in high-quality Switch-Mode Power Supplies (SMPS), industrial LED drivers, inverter stages, and server power supplies.
