Description
330µF 50V Aluminum Electrolytic Capacitor (Radial Leaded)
🧾 Product Overview:
The 330µF 50V aluminum electrolytic capacitor is a high-capacitance, medium-voltage component widely used for bulk energy storage, filtering, and voltage smoothing in power electronics. Its larger capacity makes it suitable for circuits where significant transient current support or ripple suppression is required, such as power amplifiers, power supplies, and motor drivers.
