Product OverviewThe 400V 27µF High Voltage Aluminum Electrolytic Capacitor is designed for switching power supplies and high-voltage power conversion systems requiring effective DC filtering, voltage smoothing, and energy buffering. With a 400V DC rated voltage and 27µF nominal capacitance, it provides a practical solution for high-voltage sections of modern power supply equipment. The 27µF capacitance offers increased energy storage compared with lower-capacitance configurations, making this specification suitable for circuits where stable DC voltage and effective filtering are important. It can be applied to rectifier output stages, DC bus filtering, power conversion circuits, and other high-voltage sections of electronic equipment. Typical applications include switching power supplies, AC/DC power supplies, LED driver systems, power adapters, industrial control equipment, and electronic power conversion systems. Depending on the circuit architecture, the capacitor can help smooth rectified DC voltage, buffer short-term load variations, and support stable operation of downstream switching circuits. The 400V voltage rating makes this component suitable for high-voltage DC applications, while the 27µF capacitance provides a useful balance between energy storage and component size. Final selection should consider the actual circuit voltage, ripple current, operating temperature, service life, dimensions, and mounting requirements. Key Features
