OverviewSymptomsHistoryInvestigationSee alsoFurther reading
The non-solid aluminium electrolytic capacitors with improperly formulated electrolyte mostly belonged to the so-called "low equivalent series resistance (ESR)", "low 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 current, and decreased production costs…
