    Need some info on caps

    Hi all, I need some help on finding the right caps. Im working on my Samsung plasma tv power supply. It turns on for a few seconds then turns off. These caps look bad and im wanting to replace them.

    My question is if I match them with a different make of capacitor with the same values, they should be ok right? even if they look a bit smaller?

      Should be fine as long as their ripple current is close and they're rated at 105C. What brand and series did you choose?

          This is the ones I was thinking of getting http://www.ebay.com/itm/250687678701...84.m1423.l2649

              Is there nowhere closer to you that will supply the caps, ebay/overseas spells trouble.
              Not only is it a long wait they could be cheap imitations.

                  You have digikey.com , mouser.com, newark.com in US ... forget about eBay especially with large capacitors.

                          how can I found out what the ripple current is?

                              I think Pentium4 ment dont start putting 220uf x 250v caps in the 470's hole, get the same value caps from a good known supplier you will be ok

                                      If it's not HP series, the series of those capacitors should be printed on them, maybe on the other side.

                                      Then you can just look up the datasheet.. i have an archive here:

                                      ftp://helpedia.com/pub/temp/datasheets/capacitors/

                                      If it's HP series from Capxon, the datasheet's here:

                                      470uF 250v :
                                      25mm x 41mm , 1.76A ripple current or
                                      25mm x 46mm , 1.85A ripple current

                                      These would probably work but double check diameter, space between leads, height etc:

                                      in theory from better to less better

                                      1000h-3000h @ 105c

                                      2-3000h @ 85c (that's kinda like 200-500h @ 105c, ideally you want to use 105c still)

                                                  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."
                                                  ...

                                                  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...

                                                  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,...

                                                  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?...

                                                  I did it again – I had to fulfill my inner desire to fix yet another old piece of hardware. This one is actually kind of worthwhile, too – it’s an EVGA e-GeForce 7600 GS AGP video card, model P/N: 256-A8-N542-T2. With the popularity of “retro” PCs from the Win9x to XP era going up, and the diminishing supply of decent AGP cards, it is expected their prices will go up. Or is it? I bought the this video card rather on the cheap side (~$9 USD shipped to my door), because the eBay seller listed it for parts or repair (and correctly noted the bad capacitors.)
