How to select the right aluminum electrolytic capacitor
Aluminum electrolytic capacitors assume a special position among the various types of capacitors, thanks to a high capacitance per volume and their potential use in almost any electronic system. They can be used in many applications, including energy storage and filtering undesired AC frequencies. Thanks to their high capacitance values and low impedance values, they are often used in power supplies, inverters, and DC-DC converters.
Aluminum electrolytic capacitor technology has been evolving as a result of new materials and process improvements that increase their reliability and robustness, which allows operation of up to 20 years. They are a crucial part of most electrical designs – when properly selected. But what, exactly, is an aluminum electrolytic capacitor, and how do you know how to properly select one for your projects?
