Screw Terminal Aluminum Electrolytic Capacitor 2200uF 250V
This screw-terminal aluminum electrolytic capacitor rated at 2200 µF and 250 V is a high-capacitance, high-voltage component designed for power smoothing and energy-buffering tasks. Its construction uses an aluminum can, a wound aluminum foil dielectric and a liquid electrolyte, with large terminals (screw posts) for secure, low-impedance connections. This form factor is chosen when large bulk capacitance and robust mounting are required.
In service, the device acts as an energy reservoir: when voltage is applied, charge accumulates across the dielectric, allowing rapid delivery or absorption of current spikes and smoothing of voltage fluctuations. The screw-terminal design helps minimize series resistance and inductance, making it suitable for use in circuits with significant current and switching demands. Its 250 V rating gives adequate headroom for many DC link or intermediate bus applications.
Mechanically the unit is larger than typical electrolyte types because of the high voltage and capacitance rating. The screw terminals facilitate heavy-duty connections, often using lugs or tabs rather than simple PCB links. Because it uses aluminum foil and liquid electrolyte, lifespan is influenced by temperature, ripple current and environmental stress. Proper mounting, ventilation and derating contribute to its reliable long-term use in industrial or power-electronic settings.
