Screw Terminal Aluminum Electrolytic Capacitor 12000uF 450V
The screw-terminal aluminum electrolytic capacitor rated at 12 000 µF and 450 V is engineered to serve as a high-energy buffer in demanding DC circuits, where both large charge storage and elevated voltage headroom are required. Its substantial capacitance enables the smoothing of significant DC bus fluctuations, absorbing transient surges and sustaining voltage stability when large loads switch or when ripple currents are high.
Housed in a robust metal can and equipped with screw-type terminals, this capacitor provides a reliable mechanical and electrical interface in industrial mountings. Internally the construction uses a wound aluminum foil dielectric and electrolyte system optimized for low impedance, high ripple capability, and long service life essential for heavy-duty power electronics applications.
Its 450 V rating extends its suitability into higher-voltage systems such as large inverters, high-power supplies or industrial drive DC-links, where both high voltage and high energy storage are critical. Its design supports long-duty use, high reliability, and secure connection, making it a dependable choice for systems demanding robustness and performance under stress.
Features:
- Screw-terminal connection for strong mechanical mounting and secure high-current electrical contact.
- Large capacitance of 12 000 µF at 450 V DC, delivering significant energy-storage capacity for power-electronics applications.
