Capacitor 820uF 450V
This 820µF 450V electrolytic capacitor is a robust, polarized component designed for high-voltage applications where substantial energy storage and ripple current smoothing are required. Typically constructed with an aluminum electrolyte and housed in a cylindrical aluminum can, this capacitor is engineered to handle significant voltage stress and current surges, making it a critical part of power conversion systems.
Commonly found in the primary-side filtering stages of switch-mode power supplies (SMPS), inverters, and motor drives, this capacitor helps convert pulsating rectified AC into a stable DC bus voltage. Its high capacitance and voltage rating allow it to store enough energy to maintain voltage stability during load transients and to smooth out low-frequency ripple, contributing to overall system reliability and performance.
Features:
- High capacitance and voltage rating for substantial energy storage.
- Low equivalent series resistance (ESR) for efficient ripple current handling.
- Designed for long operational life at elevated temperatures.
- Polarized design with clear negative terminal marking.
- Rugged construction for high-reliability applications.
