Electrolytic capacitors, are polarized electrochemical capacitors that achieve very high voltage values. In contrast to ultracaps, however, their capacity is many times lower. The core of an electrolytic capacitor is the anode metal, whose roughened surface is much smoother than that of a smooth surface, thus ensuring the relatively high specific capacitance. The high voltage capability of the oxidation layer and the resulting extremely thin dielectric also contribute to this.
Most frequent use of eCaps in lighting technology and automotive.
The right configuration is important
Even if the technology itself is not new and has proven itself over decades, a high-quality configuration perfectly adapted to the application is absolutely essential. If the electrolytic capacitors are incorrectly selected, they can dry out quickly and thus lose their capacity. We would be pleased to advise you on the selection and correct dimensioning of your electrolytic capacitors.
