Aluminum Electrolytic Capacitor Primer

Aluminum electrolytic capacitors utilize an "anode" (+) electrode made of high-purity etched aluminum foil. The anode etching process increases the surface area of the foil by creating microscopic tubes. This gives AE caps their high capacitance.

6 FAQs about [Skopje high voltage aluminum electrolytic capacitor bank]

What is rated voltage for aluminum electrolytic capacitors?

For aluminum electrolytic capacitors, rated voltages of 100 V are usu-ally designated as "low voltage" and rated voltages >100 V as "high voltage". For details, refer to chapter "General technical information, 15 Structure of the ordering code (part number)", page 39.

Why do aluminum electrolytic capacitors have a ripple current capability?

The equivalent series resistance of aluminum electrolytic capacitors varies with the frequency of the AC signal. As a result, the ripple current capability, which is determined by the induced power loss, is also a function of the frequency.

What is the anode of an aluminum electrolytic capacitor?

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

Can aluminum electrolytic capacitors be reverse polarized?

In most applications, aluminum electrolytic capacitors – as poled devices – are used with a DC volt-age bias of proper polarity with some superimposed AC voltage. Reverse polarities of up to 1.5 V are permissible for short periods of time as the formation of a damaging oxide layer on the cathode only starts at voltages of this magnitude.

What is a cathode in an Alumi-NUM electrolytic capacitor?

In contrast to other capacitors, the counter electrode (the cathode) of alumi-num electrolytic capacitors is a conductive liquid, the operating electrolyte. A second aluminum foil, the so-called cathode foil, serves as a large-surfaced contact area for passing current to the oper-ating electrolyte.

Why do aluminum electrolytic capacitors have a small amount of hydrogen?

One reason could be the following: During the operation of an aluminum electrolytic capacitor with non-solid electrolyte, there is a small quantity of hydrogen developed in the component. Under nor-mal conditions, this gas permeates easily out of the capacitor.
