The Hall of Shame - Badcaps Photo Montage

Wow, looks like it really popped!

I've seen these "Honsing" caps before, the vent indentations look too shallow ... no wonder why the one cap burst instead of venting like it should!

It seems that way, but where did the cap's body went lol? The cap didn't just went bad now, I had the system from 2011, I never opened it before, so it seems it worked with these messed up caps since then. Tomorrow morning I'll replace all caps in its psu, to see if the speaker problem, that started a few weeks ago, is related.

To capacitor heaven?

In all seriousness... wow, those Honsing caps must be quite bad quality to go out like that. Maybe they should be called to "Hosing" (as in, ruining the equipment they are put in.)

[Jhelms]

Glad I found this site! Could not tell you the amount of caps I have replaced over the years with splatter found all over the inside of computer cases or other. I joined as I am having a non cap related issue.. however thanks for this post - lots of nastyness!

I think LG is being a little bit disloyal to their country by not using Korean (e.g. Samyoung and/or Samwha) electrolytic capacitors - the Korean electrolytics are at least one grade higher than the Chinese electrolytics.

[Pentium4]

I think Korean capacitors are more reliable/consistent than a lot of Taiwanese caps too...I'd trust Sam Young over Teapo and Ltec

[Wester547]

Well, I think Samwha is pretty bad as of recent. Down there with Teapo/CapXon IMO, at least their low ESR series. Samyoung are okay if you keep them cool. I wouldn't put LTEC below Samyoung, though - their performance in Delta units has proven that you can make at least some of them work in PSUs if you try. I'd put LTEC above OST and OST above Teapo if we're comparing low ESR series (OST and Teapo have proven that they can definitely fail in an untimely manner even if you treat them well). General purpose series, I'd put OST above LTEC and LTEC above Teapo, if only because Teapo bulge more, not that it means much anyway.

The only "bad" brands I would honestly put above LTEC are Taicon and Hitano, TBH (although LTEC has been operating as one of Teapo's subsidiaries since April of 2005, so maybe LTEC has gone downhill since then). I'd tie Elite/Chinsan with LTEC (Elite are out of Thailand, however). Of course they are all unreliable and inconsistent compared to the Japanese brands but even some of those brands have proven that they can mess up and very badly at that, ala KZG/KZJ. That said, at least those previously awful ultra low ESR wet electrolytics are discontinued. Also keep in mind that these Korean brands are headquartered in Korea but do have factories in China and likely adopt and use many materials from there (IE materials processed in-house), although Samwha do import their aluminum foil from Japan if you could believe that. Older Samwha and Samyoung aren't so bad - I've seen 20+ year old VCRs and SCSI devices with them chugging along just fine. Samyoung is NCC's Korean subsidiary and Samwha Nichicon's, so those things may help.

Here are three bulged Ltecs (and one that looks okay) in my Netgear WNDR3700v1 wireless router. The upper left and lower right panels are of the same capacitor.

Un ventilador de 8cm me parece un poco chiquito para remover el calor que va a generar el PSU. Si fuera algo mas grande o por lo menos otra marca que esa duraria mas.

Pero yo lo repararia por lo menos para 200-250 vatios
(Still i would fix it for at least 200-250 watts)

(Y que viva España)

Ok, al final no la repare, porque se me fastidio el soldador, además tengo varias FSP, y de momento no me corre prisa en repararla.
Igualmente gracias, y por las molestias en escribir en español
Bye

Bad Samxom cap from lg lcd monitor:

[Jooo]

Mainboard of a Philips Blu-ray player, several bulging Chang capacitors, including some ventless ones. This was one of their higher end players.

[momaka]

^ Ouch. Judging by those coils, the Chang capacitors above are probably filtering buck regulators - and that can't be good for them.
Also makes you wonder what is in the lower-end players if this is a "higher" end .

Looks like that video card was built to fail on purpose. If the bad OSTs aren't enough for you, it also has Chemicon KZG and a tiny heatsink with no fins. Oh, and those GeForce 8x00 series do have the bumpgate issue, so that heatsink is not helping at all.

Interesting how Dell (or rather Foxconn?) used good polymer caps on some of these (like the one I have in my 170L) and KZG in others.

Speaking of KZG, I had one 820 uF 6.3V KZG fail on a P5GC-MX while sitting unused in storage for a year. This was back in October. Yesterday, I had a look at that motherboard again, and another 820 uF 6.3V KZG has failed again, all on its own. I guess it is only a matter of time before others bulge on that motherboard. It's had something like 50k hours on the clock, though. So not too bad overall. I guess KZG doesn't like to sit unused more than anything else.
