6 FAQs about [Composition of Aluminum Electrolytic Capacitors]

What is aluminum electrolytic capacitor?

1. General Description of Aluminum Electrolytic Capacitors An aluminum electrolytic capacitor consists of cathode aluminum foil, capacitor paper (electrolytic paper), electrolyte, and an aluminum oxide layer, which acts as the dielectric, formed on the anode foil surface.

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.

What are the different types of electrolytic capacitors?

Electrolytic capacitors are available in several types as aluminum, tantalum, and niobium versions (Ho et al., 2010). The internal structure of an aluminum electrolytic capacitor consists of two aluminum foils, which are separated by a porous material such as paper which is impregnated with an electrolyte as shown in Fig. 6.11.

Are aluminum electrolytic capacitors polar or non polar?

If both the anode and cathode foils have an oxide film, the capacitors would be bipolar (non-polar) type capacitor. These technical notes refer to "non-solid" aluminum electrolytic construction in which the separator is impregnated with liquid electrolyte. There is another type of aluminum electrolytic capacitor that uses solid electrolyte.

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.

Why do aluminum electrolytic capacitors have non-solid electrolytes?

Aluminum electrolytic capacitors with non-solid electrolytes have an exceptional position among electronic components because they work with an electrolyte as liquid ingredient. The liquid electrolyte determines the time-dependent behavior of electrolytic capacitors. They age over time as the electrolyte evaporates.
