What is an aluminum electrolytic capacitor?

As is the case with all capacitors, an aluminum electrolytic capacitor comprises two electrically conductive material layers that are separated by a dielectric layer. One electrode (the anode) is formed by an aluminum foil with an enlarged surface area. The oxide layer (Al2O3) that is built up on this is used as the dielectric.

What is a cathode foil in an electrolytic capacitor?

A second aluminum foil, the so-called cathode foil, serves as a large-surfaced contact area for passing current to the operating electrolyte. The anode of an aluminum electrolytic capacitor is an aluminum foil of extreme purity.

What is the anode of an aluminum electrolytic capacitor?

The anode of an aluminum electrolytic capacitor is an aluminum foil of extreme purity. The effective surface area of this foil is greatly enlarged (by a factor of up to 200) by electrochemical etching in order to achieve the maximum possible capacitance values.

Why should you choose TDK aluminum electrolytic capacitors?

The TDK aluminum electrolytic capacitors feature outstanding ripple current capabilities and very long-term reliability. Design flexibility and engineering expertise allow TDK to offer custom specific solutions. The capacitance of aluminum electrolytic capacitors is defined by the surface of the aluminum anode foil.
