Geee. I would take a few brain cells to conclude your cap was defective if
it burped. Ya' think that would be cause you have conductive electrolyte? Maybe the electrolyte was full of carbon after the internal fault?

Are you an electrician too? You truly amaze. This is the second bit of misinformation in just a few hours. Electrolytes make pretty GOOD conductors. That's probably WHY they are called electrolytes. Now, sometimes we DON'T want current to flow, so the **DIELECTRIC** was invented. In some (all?) electrolytic caps, the dielectric is an oxide layer.. This is a very thin layer that allows good storage capacity in a smaller physical size. The conductive electrolyte makes up the negative side of the thing. http://www.tpub.com/neets/book2/3f.htm How does it feel to know so much and be WRONG about all of it? mike -- The trouble with people is not that they don't know but that they know so much that ain't so. ~Josh Billings |

CM SOME leaking electrolytes are corrosive when "in the wild". When electrolytic caps short is is due to "thorns" growing on the plates and punching through, shorting the plates together. Then they heat up and blow. When they go, they often take out other components around them. |
