    General Cap question

    When replacing caps should you generally stay within the same type of cap? More specifically if the caps that need to be replaced are general-use types of caps should you replace them with the same type or go for low-esr caps? I am asking because I am going to recap a Linksys WRT54G that has some crappy Hermei caps. You would think that since Linksys is a division of Cisco that they would use good caps inside their products; I guess maybe the general consumer division is a exception .

      Re: General Cap question

      there are general use caps, even some 85oc caps which are not too bad specs. therefore be careful if you spot general use caps and replace them with quite inferior replacements.

      you should use low esr caps inside that unit. they dont even have to be the lowest esr. best to go with something with more endurance especially if that unit is quite toasty inside or you will install it outside.

      cisco products are many times more expensive and better caps, better quality, go figure.

          Thats true, Got a box of dead linksys routers to prove it.

              then again anything cisco requires a significant amount of bookreading to get the full benefit of it. goddamn IOS syntax

                  I have replaced those caps in my wrt54g with some 1500uf Rubycon MCZ. Sure in any way overkill, but it works. Some 470uf long life low esr typ should be the better way to do the job. If you can get some i suggest Panasonic FC or the long life series from Rubycon. For this unit some regular 105°c should be fine too.

                      chemicon LXZ/LXY, nichicon HE, and rubycon YXF is my favorit for those tasks. they can even have the endurance of 10k hours at 105C.
                      days are so short when you actually do something..

                          Just FYI I have setup a few dozen Linksys WRT54GS AP's, plus seen many on forums

                          Never seen one with a badcap...

                              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).

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

                              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?...

                              Replacing electrolytic caps by solid caps on old motherboards
                              by madscientist750
                              I do have several old pc motherboards which i recapped 10 year ago and some of those caps are bulged now.
                              I would like to upgrade them using solid capacitors. I do use them for testing and helping some alternative operating systems.
                              I would like to ask if such an upgrade can be done, what should i have in mind when replacing electrolytic by solid caps and if such thing exist, if there are caps list for old motherboards. I would have to figure out what caps needs each motherboard and then prepare a list to try to ask for them on some electronics stores.
