Austria Super Aluminum Electrolytic Capacitor

What are aluminum electrolytic capacitors made of?

In aluminum electrolytic capacitors, the anode and cathode consist of highly roughened aluminum foils, whereby the roughened anode foil with the dielectric layer is rolled up between an absorbent material (usually paper).

Are aluminum electrolytic capacitors a good choice?

Aluminum electrolytic capacitors are an attractive solution here since they can fulfill the key requirements, such as high voltage ratings of up to 500 V, large capacitance of up to 820 µF and high ripple current capabilities at an operating temperature range of -40 °C to 105 °C.

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.

What is hybrid polymer technology in aluminum electrolytic capacitors?

In the field of Aluminum Electrolytic Capacitors, the Hybrid Polymer technology offers higher ripple current densities by a factor of, e.g., 5x compared to standard Liquid Electrolyte technology.
