    Need help identifying these "polymer" caps

    See attachment below. This type of capacitor used to appear on MSI's LGA775 motherboards. The motherboard taken as an example is P31 Neo-F and you can see them in CPU's VRM output stage:

    Sometimes they're replaced by OST's RLA series (in blue sleeve) electrolytics so I suspect they aren't polymers?

    It's also interesting to see that MSI used Japanese capacitors in the "non-critical" areas of this inexpensive motherboard, like:

    PCI power filtering and chipset power

    Memory power

    So they're somewhat better than these Japanese counterparts?

      Those are not polymer... PCBONEZ was kind to inform me that those are Panasonic FL... The "vent" is a plug in the bung, on the underside of the cap...

              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...

              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."
              ...

              GeForce 6800GT recap, need help identifying caps and finding replacements
              by fl0w
              Hi,

              I just noticed that my Asus V9999GT (GeForce 6800 GT) had some swelling capacitors. I managed to identify the brown ones, which are Nippon Chemi-Con KZG series, 6.3V 820µF, which I plan to replace with this.
              But for the yellow ones, I guess these are Fujitsu caps, without being able to identify which series... A picture of the video card is attached to the topic.

              I need to replace:
              • 2x 2.5V 1500µF => I plan to use this
              • 2x 16V 330µF=> I plan to use this
              • 1x 6.3V 680µF=> I plan to use this
              Am I correct with the cap choices?

              Thanks for...

              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?...
