Product OverviewThe 400V 22µF Compact High Voltage Aluminum Electrolytic Capacitor is designed for switching power supplies and other high-voltage power conversion circuits where stable DC filtering, voltage smoothing, and efficient use of installation space are important. Featuring a 400V DC rated voltage and 22µF nominal capacitance, this capacitor provides a practical combination of high-voltage capability and moderate energy storage. The compact design makes it suitable for power supply equipment where PCB space and component layout need to be carefully managed. The capacitor can be applied to switching power supplies, AC/DC converters, LED driver power supplies, adapters, industrial control equipment, and high-voltage DC circuits. In rectifier and power conversion stages, it can help smooth pulsating DC voltage and provide local energy buffering for downstream circuits. Its 22µF capacitance offers greater energy storage than lower-capacitance 10µF or 15µF configurations while maintaining a relatively compact specification. This makes it a useful option for designers balancing capacitance requirements, voltage rating, installation space, and overall power supply architecture. For final application selection, engineers should verify the actual operating voltage, ripple current, temperature conditions, service-life requirements, dimensions, and mounting configuration against the manufacturer's technical specifications.
