    Replacing FZ78 with a solid capacitor

    Can someone tell me what capacitors can I use for replacing the FZ78 (1000uF 6.3V) on my video card (Forsa Nvidia Geforce 9600GT)?
    Can I replace them with solid capacitors? If yes what models would you recommend?

    Thanks!

    usually these

    but tc's out right now

    You should have no problem using lytics though

    these should be fine

    though i'm not sure what height/radius those on your card are. I bet they're under 14mm though

      Hey,
      Thank you for reply but I've said FZ78 (1000uF 6.3V) :p
      Anyway I will wait for others tips.

        Re: Replacing FZ78 with a solid capacitor

        When you replace solid capacitors (polymers) with electrolytic capacitors, it's often recommended to go up a bit in capacity.
        Also, for the purpose that capacitor was used, going up in capacity a bit won't cause problems. The capacity needs to be just over a minimum value.

        So the 1500uF Rubycon capacitor that he recommended is a very good choice to replace that Sacon FZ.

        If you have to get 1000uF 6.3 here's what will work...
        ...but since you had to be a jerk and didn't enter the country you're in, i can only recommend alternatives for US

            You kinda seem to forget that Sacon FZs are lytics.. :P
            No need for increased capacitance.

            I've attached the datasheet of those junk caps for specs comparison..

              No, I knew it's electrolytic. I clarified that through private messages, he contacted me privately.

              When this series was made, the specs were more or less in the polymer/solid capacitors range... nowadays those specs are achievable by some electrolytics, though kinda hard at that height...

                If you're gonna use fleabay, only ever use sellers egekecu/PCMCS or Audjade. Many others sell fakes.

                As for your original question, use http://www.ebay.com.au/itm/4-Nichico...item45fdff1b5c to replace the FZs. The slight capacitance drop shouldn't be a problem.
                I love putting bad caps and flat batteries in fire and watching them explode!!

                No wonder it doesn't work! You installed the jumper wires backwards

                  If you were going there then they also have 6.3 v1000uF

                    Re: Replacing FZ78 with a solid capacitor

                    how about measuring the voltage at the caps you wish to replace?then i can suggest something based on my experience.something you can buy at the badcaps store and skip the ebay minefield.

                      Re: Replacing FZ78 with a solid capacitor

                      you can go up or down in cap within reason with polys. Actually i've seen people who replace 1500 with 330 or 560 16v caps on input vrms before with no problem

                      lytics are another story. Usually same or higher, but within reason

                        I've replaced the bad capacitors with original Panasonic 1000uf 16V.
                        The big thanks goes to Mariushm.
                        Anyway thanks for the answers people

                          I replaced some capacitor which is located on optical pickup pcb which is shown in the table below(PCB #2).Because it have been out of order.
                          Now,It works very well,But I just have found that all caps (6svpc100my and other part number as well) ,which is shown in the table below, has ultra-high ripple current spec.
                          It is not able to obtain any capacitor which can be a substitute for this ultra-high ripple current nichicon capacitor.
                          So I replaced it with samxon and rubycon's general capacitor(GP,YXA series).
                          I know that these capacitor will not last as long as nichicon capacitor...

                          I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
                          I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm

                          And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.

                          When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.


                          Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
                          But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.

                          by cybernet3000
                          Hello all,

                          Got a bit of a noob question - I have an original XBox revision 1.0 with a Foxlink FTPS-0001 Rev B psu. I've already removed the infamous clock capacitor and I'm planning on replacing the caps around the big heat sink (Thanks to everyone who contributed to that massive thread for pointing me in the right direction) but I also noticed on the PSU there's one large cap that seems to be bulging a little. It is cap C19 and from my googling I've been able to determine it's a 2200 uF 10 V capacitor.

                          My questions are:
                          1) Can I just replace this with any...
