    Worst Caps I have ever seen: TK (Total Krap?)

    I decided to recap this AM2 motherboard I pulled out of a little COMPAQ box I bought as non-working. The mobo is an MCP61PM-HM.

    There are 10 1800uf 6.3v caps on this board. One is Suncon(Sanyo) the remaining 9 are TK. Three of the TK were bulging. I yanked all the TKs, then measured them with my ESR meter and Capacitance meter.

    The ESR readings varied from .08 to .012 on the non-bulged caps.

    The Capacitance readings on all the "good" ones were 85 to 100 !!

    This machine dates to 2009 I believe.

    By far the worst caps I have ever seen!

      Yea, that series is equivalent to Nichicon HM IIRC or Rubycon MBZ, Suncon WG, Samxon GD.

      Toshin Kyogo. Taiwanese caps branded as Japanese. Probably OST caps under the sleeve.

          No, they have a somewhat different vent to OST. I will argue to the death that they are made in Japan and are simply distributed by OST. Country of origin has absolutely nothing whatsoever to do with reliability. It just happens to be the case that most of the good brands are from Japan.

          Btw, I always say that TK stands for Terrible Kapacitor, and OST for Only Some Trash.
          I love putting bad caps and flat batteries in fire and watching them explode!!

              If they were rated for 250 or 500 hours at 85C, they won't last long in a hot system.

                  Replacing the 8 TKs restored the mobo to health.

                  Every other cap on the board is an OST, so there may indeed be a connection.

                  So BAD that OST won't put their own name on it?

                      And the country where the Corporate Office is located has nothing to do with where their products are made.
                      .
                      TK has factories in China and Taiwan since about 2002 and my guess is they've been getting electrolyte and so forth from OST.
                      .
                      TK - small
                      OST - big

                          Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!
                          by momaka
                          I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

                          For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

                          https://www.badcaps.net/filedata/fetch?id=3591772

                          It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

                          Heathkit IO-4205 Power Supply Caps
                          by eryjus
                          Hello,

                          First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                          I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                          I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
                          ...

                          Identifying caps on an old Zoom 9000
                          by Paxman_Swede
                          Hello!

                          I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

                          The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

                          I have studied the board and...

                          Help with switching power supply caps
                          by captain150
                          I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
                          I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...

                          Gigabyte GA-6OXT :: caps question
                          by Foetuss
                          Good evening

                          I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
                          Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?

                          But I was also suprised about the bigger boys, which are 330µF 25V.
                          Could it be they used 25V caps because they were cheaper / available at that time?...
