Default Re: KZG - KZJ - Same Electrolyte

In Aluminum Electrolytics the Aluminum Oxide layer -IS- the Dielectric.
The separator paper is only in there to act as a carrier [flow path sort'a] so the electrolyte can get to the Aluminum to keep it oxidized.

Ripple currents blast chunks [figuratively] of the Oxide [or Aluminum depending on instantaneous polarity] into solution where it disolves.
The DC voltage present restores the damaged areas similar to how electroplating works.
- That's why electrolytics used to be called 'self healing capacitors', although the term has fallen out of use over the years.
