An aluminum electrolytic capacitor consists of a wound capac-itor element, impregnated with liquid electrolyte, connected to terminals and sealed in a can. See Figures 1 and 2. Voltage ratings are classified as < 100 VDC for low voltage, 101-250 for mid-voltage and 251-700 for high voltage.
Our aluminum electrolytic capacitors can be stored without damage at ambient temperatures rang-ing from typical –55 °C up to the upper category temperature. However, it must be taken into account that storage at elevated temperatures will affect leakage cur-rent, useful life and solderability.
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.
Aluminum electrolytic capacitors with non-solid electrolytes normally can be charged up to the rated voltage without any current limitation. This property is a result of the limited ion movability in the liquid electrolyte, which slows down the voltage ramp across the dielectric, and the capacitor's ESR.
The buffer layer A can effectively barrier the interfacial atomic diffusion of SnO 2 /AAO and repair AAO dielectric gaps, thus guaranteeing high performance and reliability of MIM-type aluminum electrolytic capacitors. Furthermore, its MIM dielectric capacitor model enable fast charge-discharge with high power density .

The reliability prediction of aluminum electrolytic capacitors is generally expressed as a Failure rate λ, abbreviated FIT (Failures In Time). It is a measure of the number of failures per unit hour during the time of constant random failures in the bathtub curve. The flat part in the bathtub curve corresponds with the calculated lifetime or service life of non-solid electrolytic capacitors. The fail…
