In Reply to: What factors degrade electrolytic filter caps? posted by DaveD on May 8, 2007 at 13:42:04:
the simple version of the way most electrolytic caps work is: there's an anode and a cathode, one is a post and the other the liquid in it. For a dielectric to separate the two and create capacitance, they rely on some type of oxide to form on the post while current is flowin, and this oxide *is* the dielectric. It takes some operation to initially form the caps, and continued operation to keep them formed. If they are good quality caps they might last 30-40 years if they are kept formed.
