===Common characteristics=== The non-solid aluminium electrolytic capacitors with improperly formulated electrolyte mostly belonged to the so-called "low [[equivalent series resistance]] (ESR)", "low [[Electrical impedance|impedance]]", or "high ripple current" e-cap series. The advantage of e-caps using an electrolyte composed of 70% water or more is, in particular, a low ESR, which allows a higher [[Ripple (electrical)|ripple current]], and decreased production costs, water being the least costly material in a capacitor.<ref name=Uzawa>{{cite journal |last1=Uzawa |first1=Shigeru |last2=Komatsu |first2=Akihiko |last3=Ogawara |first3=Tetsushi |last4=Rubycon Corporation |title=Ultra Low Impedance Aluminium Electrolytic Capacitor with Water based Electrolyte |journal=Journal of Reliability Engineering Association of Japan |date=2002 |volume=24 |number=4 |pages=276–283 |id=Accession number 02A0509168 |issn=0919-2697}}</ref> {| class="wikitable centered" |+ Comparison of aluminium e-caps with different non-solid electrolytes !Electrolyte !Manufacturer<br/>series, type !Dimensions<br>D × L<br>(mm) !Max.
