We have a switching power supply that is made by another manufacturer and after 6 months to 2 years they fail. They are all low ESR. Jamicon and Hermei are the ones we have the most problems with, and switched to Nicholsen(sp) and stopped having problems. There are 3 470 uf 1 1000 uf and a 2200 uf that always fail at the same time. Although we still have a bunch still come in for repair that used the old caps before we found the problem. In the last 2 years we have yet to have a repaired board come back (with a problem), at least I don't consider a blown fuse with the spare right on the board a problem since it fuses the output of the power supply itself, so if it's blown it's another card and it's usually a Tant. cap or one of the other surface mount caps that are shorted.

That is reminiscent of the problems with computer motherboards several years back. I forget the full details, but was related to the electrolyte formula being "bad" or something. Would work fine at first, but would fail fairly soon. Motherboard caps would start puffing or even pop (and that stinks).
