Screw Terminal Aluminum Electrolytic Capacitor 2200uF 450V
This screw-terminal aluminum electrolytic capacitor rated at 2200 µF and 450 V is built to provide large energy storage and smoothing capability in high-voltage DC circuits. Its robust construction employs an aluminum can, wound foil and liquid electrolyte, combined with screw-type posts for secure connections. The 450 V rating gives it substantial headroom for DC bus or high-voltage link applications, enabling it to absorb and deliver current surges and stabilize voltage.
In active use, the capacitor acts as a buffer: when a power conversion stage feeds a DC bus, this capacitor helps absorb ripple, mitigate voltage dips, and supply transient current when loads jump. The screw-terminal format reduces parasitic resistance and inductance compared with simpler terminations, supporting cleaner, higher-current paths and making the part suitable for heavier-duty power electronics or industrial systems.
Mechanically, the device is larger than lower-voltage types, often featuring a substantial diameter and height to house the required foil and electrolyte volume. The screw posts enable ring lugs or heavy busbar connections rather than light wires. Because aluminum electrolytics’ lifetime is influenced by temperature, ripple current, and voltage stress, proper mounting, ventilation and ambient control are important to maximize service life. The rugged packaging makes it well-suited for bench or rack-mounted power supplies, inverters, or industrial converters.
