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… Weban inability to easily expand under pressure. Capacitors used in RF or sustained high current applications can overheat, especially in the center of the capacitor rolls.
