Farnell offers a comprehensive range of aluminium electrolytic capacitors, designed to provide high capacitance and reliable performance across a variety of demanding applications. Our selection includes hybrid polymer, leaded, SMD, and snap-in/screw-terminal aluminium electrolytic capacitors, suited for both high-power industrial systems and compact electronic devices.

Aluminium electrolytic capacitors are widely used in applications where large capacitance values are essential. Their design includes an electrolyte and a thin layer of aluminium oxide as the dielectric, enabling high capacitance in a compact form factor. These capacitors are ideal for power supply filtering, DC voltage smoothing, and buffering, especially in DC-DC converters and industrial power supplies.

With a range of capacitance values, ESR ratings, and temperature tolerances, our aluminium electrolytic capacitors offer reliable performance under high-stress conditions. Their ability to handle large voltage loads with low leakage makes them well-suited for automotive electronics, audio systems, and other high-demand environments.

For specific needs, our hybrid polymer options offer lower ESR and higher ripple current ratings, providing additional stability and longevity at higher frequencies. Choose Farnell for a versatile lineup of aluminium electrolytic capacitors designed to meet the needs of modern electronic applications.
