Until the wound construction of aluminum foil capacitors, this type of capacitor was bulky and heavy. There are different sizes of capacitor ranging from 3 mm in diameter for 5 mm in height up to 90 mm for 210 mm .
In comparison to other dielectric, similar voltage endurance is provided by dielectrics even if thickness ("d" in the above formula) is thin. By etching the surface of aluminum foil, the effective area of the foil can be enlarged 80~100 times for low voltage capacitors and 30~40 times for middle / high voltage capacitors.
The aluminum foil which forms the anode of the capacitor will have its surface chemically highly etched to increase its surface area, and therefore its capacitance.
Only during the late 1930s the hard-rolled aluminum foil was found to be able to provide capacitor anodes of improved capacitance. This property had not found any use until the 1960s when the aluminum electrolytic capacitor first appeared in the electronic industry.
