The engineer''s guide to aluminum electrolytic capacitors
Aluminum electrolytic capacitors, often called electrolytic capacitors, are usually selected because they offer a relatively large capacitance for a relatively small physical size. Aluminum electrolytic capacitors tend to be readily available, and with high voltage values (on the order of 700 V). These polarized capacitors usually have a wide tolerance (± 20%), …
Contact UsAluminum Electrolytic Capacitors
The capacitance of aluminum electrolytic capacitors is defined by the surface of the aluminum anode foil. This surface is maximized by special etching processes, giving these capacitors the highest volumetric capacitance of all capacitor technologies and thus an attractive cost per capacitance ratio.
