1000uF 250V Electrolytic Capacitor

1000uF 250V Electrolytic Capacitor 

The 1000uF 250V Electrolytic Capacitor is a robust, high-energy storage component engineered for demanding high-voltage power applications. Designed using high-quality aluminum foil and electrolyte, it offers excellent capacitance stability, low leakage current, and reliable performance under continuous operation.

This capacitor is commonly used in AC mains rectification circuits, where the rectified output voltage reaches around 310V DC (from 230V AC). Its 250V rating makes it suitable for intermediate bus voltages, PFC circuits, and industrial-grade power supplies requiring large bulk capacitors for smoothing the DC rail.

Because of its low ESR (Equivalent Series Resistance), it efficiently handles high ripple currents, reduces noise in power lines, and provides stable DC output. The rugged cylindrical metal can design ensures heat dissipation and long service life, even in harsh operating environments.

It is widely used in professional electronics such as inverters, motor controllers, high-power audio amplifiers, LED lighting systems, and industrial SMPS units. Its high capacitance allows it to act as an energy reservoir, preventing voltage dips during sudden load changes and ensuring smooth, uninterrupted operation of the equipment.
