What is an Aluminum Electrolytic Capacitor?

An electrolytic capacitor is a capacitor that uses an electrolyte as one of its plates in order to achieve a larger capacitance per unit volume than other types of capacitors. In aluminum electrolytic capacitors, the dielectric is a thin layer of aluminum oxide. The large capacitance of electrolytic capacitors makes them suitable for passing or bypassing low frequency signals as well as storing large amounts of energy. Aluminum electrolytic capacitors are widely used in power supplies and for decoupling unwanted AC components from DC power connections.

Types of Aluminum Electrolytic Capacitors

There are many different kinds of aluminum electrolytic capacitors and at Future Electronics we stock many of the most common types categorized by capacitance, lifetime at temperature, type, maximum operating temperature, case size / dimension, operating temperature range, rated voltage, series, packaging type and ESR. The parametric filters on our website can help refine your search results depending on the required specifications.

The most common sizes for capacitance are 10 µF, 47 µF, 100 µF, 220 µF and 470 µF. We also carry aluminum electrolytic capacitors with capacitance as high as 10000000 µF. Rated voltage can be between 2 V and 450 kV, with the most common aluminum electrolytic capacitors having a rated voltage of 25 V, 35 V or 50 V.

Applications for Aluminum Electrolytic Capacitors:

Aluminum electrolytic capacitors have several practical, everyday applications. The most commonly found applications include filter capacitors for power supply outputs, motor start and non-polarized capacitor applications, blocking and dc-bypass circuits, audio applications, photoflash and strobe capacitors and energy discharge capacitors. Aluminum electrolytic capacitors can also be found in LED lighting applications.

Choosing the Right Aluminum Electrolytic Capacitor:

When you are looking for the right aluminum electrolytic capacitors, with the FutureElectronics.com parametric search, you can filter the results by various attributes: by Capacitance (10 µF, 47 µF, 100 µF, 220 µF, 470 µF,…), Maximum Operating Temperature (70 °C, 85 °C, 105 °C,…) and Rated Voltage (up to 450 kV) to name a few. You will be able to find the right aluminum electrolytic capacitor in small and large sizes from several manufacturers that can be used as miniature aluminum electrolytic capacitors, audio grade electrolytic capacitors, multi section electrolytic capacitors, axial electrolytic capacitors, radial electrolytic capacitors, computer grade electrolytic capacitors, reforming electrolytic capacitors, non-polar electrolytic capacitors or low ESR electrolytic capacitors.
