Chad Super Aluminum Electrolytic Capacitor

What is the capacitance of aluminum 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.

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.

Can aluminum electrolytic capacitors withstand rapid charging?

Aluminum electrolytic capacitors can generally withstand rapid charging along with occasional overvoltage transient spikes of lim-ited energy. If transients above the capacitor’s rated DC voltage are anticipated in the application, please contact us to discuss the best capacitor for the application.

Are aluminum electrolytic capacitors reliable?

Aluminum electrolytic capacitors are generally divided into two basic reliability categories: capacitors for high-reliability applications and capacitors for general-purpose applications. This differentiation has also been adopted in the relevant IEC standards.
