One of the major axes of research on electrolytic capacitors is the aluminum electrolytic capacitor (AEC). They have higher volume efficiency due to a significantly lower minimum dielectric thickness than all the other capacitors. However, they have a high internal resistance as well as an inductance limiting high frequency performance and low ...
Aluminum, which is main material in an aluminum electrolytic capacitor, forms an oxide layer (Al2O 3) on its surface when the aluminum is set as anode and charged with electricity in elec-trolyte. The aluminum foil with an oxide layer formed thereon, as shown in Fig. 5, is capable of rectifying electriccurrent in elec-trolyte.

Nevertheless, the following rules should be observed w hen handling aluminum electrolytic capacitors: No electrolyte should come into contact with eyes or skin. If electrolyte does come ...
An aluminum electrolytic capacitor is a polar component that needs strictly to be mounted under correct polarity. With our PAPR terminal style (Protection Against Polarity Reversal) we offer an optional mechanical feature in addition to the visual polarity marking on the cover disk and the sleeve, which prevents from mounting in reverse polarity.
Except for a few surface-mount technology (SMT) aluminum electrolytic capacitor types with solid electrolyte systems, an aluminum electrolytic capacitor consists of a wound capacitor element, impregnated with liquid electrolyte, connected to terminals and sealed in a can.
