150uF 450V Electrolytic Capacitor 150uF 450V

Product Overview

The 150µF 450V electrolytic capacitor is a heavy-duty, high-voltage polarized through-hole component. Typically manufactured in large radial leaded or "snap-in" form factors, this capacitor is engineered specifically for primary-side AC mains rectification, bulk energy storage, and Power Factor Correction (PFC) filtering in robust power systems.

Because rectified 220V/240V AC mains power produces a DC bus voltage of approximately 310V to 340V DC, a 450V rating is the industry standard required to provide the necessary safety headroom against line voltage fluctuations and transient surges in Switch-Mode Power Supplies (SMPS), industrial inverters, and motor drives.
