I am a member of badcaps.net for a long time and it's the first time I see that list. It's either from an old thread or it's extracted from a thread with relevant information removed.
There are a few brands there in the list that don't deserve to be there - they are probably there because a number of failures were reported by people repairing stuff, but that's usually due to bad design of the product they're in, not the capacitors themselves.
For example..
Fujitsu - they made functional polymer capacitors, nowadays they're absorbed by Nichicon and the series is nichicon fp-cap . Good capacitors, probably some dell machines died due to heat so they show on the list
OST - bad electrolytic capacitors (used a lot on socket 462 and socket am2 boards, some older power supplies) but their polymer capacitors are (very) good, they are used a lot in new products
Partsnic - daewoo capacitors ..probably show up in the list because some moron designer used a general purpose series as a low esr or in an area with high heat or current ripples.
Su'scon - used a lot in LG monitors and other monitor brands in general, in some power supplies, in some routers or switches that don't have ventilation etc ... seems they fail more often in some countries due to humidity perhaps, in other countries they don't have reported problems. They do fail, but not as much as the other chinese shit in the list.
Taicon - this is really a good brand, it's a factory in Taiwan that's part owned by Nichicon. Used A LOT by Delta and Enhance (makes server psus) in their power supplies and they're fine. Probably were a few reports of blown Taicon capacitors so they showed up in the list.
Teapo - huge manufacturer of capacitors with good quality capacitors. A few particular low series of capacitors (one or two with very low diameter capacitors) tend to dry up or go bad in power supplies and motherboards due to heat, but if you avoid those series with failure reports the other series are fine. Japanese manufacturers like Nichicon, Nippon Chemi Con etc also had problem series so it's not fair to blacklist a company like Teapo just because it has it's problem series.
Teapo is probably the most common capacitor brand after the japanese ones, they sell a lot of capacitors and I would rate them just behind the Japanese manufacturers and in the same class with Taicon.
If it's a list of brands that had failures, like I said.. even Nichicon or Nippon Chemi Con would have to be added to the list, and they're very good manufacturers.
rolandpenplotter: "con" comes from the old name for capacitors, which is "condensator" or
condensateur ... Nichi
con , Ruby
con, Nippon Chemi
Con all reputable Japanese manufacturers.
