An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor.
Water-based electrolytes with high water content, up to 70 % water for low impedance, low ESR or high ripple current electrolytic capacitors with voltage ratings up to 100 V for low cost applications . ESR and ripple current will be described below, in capacitors these parameters are linked to internal heating.
Their characteristics change strongly with frequency, temperature and aging time. Electrolytic capacitors are among the components whose lifetime has the greatest influence on the reliability of electrical systems. Over the past three decades, many efforts in academic research have been devoted to improving reliability capacitor.
They use the FIT specification with 40 °C and 0.5 U R as reference conditions. aluminium electrolytic capacitors are very reliable components. Published figures show for low voltage types (6.3…160 V) FIT rates in the range of 1 to 20 FIT and for high voltage types (>160 …550 V) FIT rates in the range of 20 to 200 FIT.
In order to predict the trend of electrolytic capacitors, one can imagine a hybrid electrolytic capacitor, a technology that would combine the advantages of electrolytic capacitors such as high electrode surface (pressed and sintered, porous, …) with a composite hybrid dielectric structure to achieve greater specific energy .
The dielectric thickness of electrolytic capacitors is very small, in the range of nanometers per volt. On the other hand, the voltage strengths of these oxide layers are quite high. With this very thin dielectric oxide layer combined with a sufficiently high dielectric strength the electrolytic capacitors can achieve a high volumetric capacitance.
