The size of commercially available capacitors ranges from around 0.1 pF to 5 000 F (5 kF) supercapacitors. Parasitic capacitance in high-performance integrated circuits can be measured in femtofarads (1 fF = 0.001 pF = 10 −15 F), while high-performance test equipment can detect changes in capacitance on the order of tens of attofarads (1 aF ...

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 [ 88 ] and for high voltage types (>160 …550 V) FIT rates in the range of 20 to 200 FIT. [ 86 ]

Because activated carbon electrodes have a very high surface area and an extremely thin double-layer distance which is on the order of a few ångströms (0.3-0.8 nm), it is understandable why supercapacitors have the highest capacitance values among the capacitors (in the range of 10 to 40 μF/cm 2).
