Here's a more complete listing of manufacturers who have had/are having quality issues with electrolytic capacitors.
In case this site gets nuked, here are the listed manufacturers:
Commonly failed capacitor brands
- Tayeh (A brand that does not appear to exist, indicating the actual manufacturers were wary of putting their name on their product; and probably a fake of "Ta-Keh", a genuine maker of high-end capacitors for audio equipment, used by Denon) * Chhsi * Teapo (Teapo has denied these claims, and evidence suggests their new capacitors are sound, however their older ones appear to suffer from the same problems other brands do) * I.Q. * Rulycon (A clone of "Rubycon", a well-known manufacturer of high-quality capacitors, right down to the exact style of the cases and the fonts used for lettering) * JPCON * Jackcon (The only capacitor manufacturer to own up to their mistake; they are also the only one to issue free replacement capacitors to people who had theirs fail. Their new products appear to be of greater quality.) * JDEC * CTC * (G) Luxon (also G-Luxon) * Gloria * Raycon * Hermei * Choyo * GSC * Nrsy (only with X-shaped vents. The new NRSY capacitors have K vents and are a genuine, high-quality Nippon-made part.) * Fuhjyyu (found in Antec power supplies to this day)
As of May 2005, some evidence
(I've actually seen a Dell P4 motherboard that had failing Nichicon parts!)
