    Replace capacitor...

    Hello,
    Ik am a newbie in this but i want to try this: I have a 3A 12V psu from a lcd and it has a bad 400V 47uF cap. I don't have 400V 47uF caps but i do have 2 200V 300uF caps from a chinese pc psu. Can i replace that bad cap with 2 200V 300uF caps so i have 400V 300uF? Or is it bad to replace a 47uF cap with a 300uF cap?

      No, you would need a single 400V capacitor. You could increase the capacitance a little though if you wanted.

          OK, thanks for your answer. The only option is buying a new cap then...

              You should check but I believe that to get 2 caps to = 400v in a DC circuit you have to connect them in series. 2 300uf caps connected in series would have a total uf of 150uf.

                  Capacitor detached from PCB – RTX 2070 Super Founders Edition
                  by MORETTIGIAN
                  Title:
                  Capacitor detached from PCB – RTX 2070 Super Founders Edition

                  Description:
                  During maintenance on an RTX 2070 SUPER Founders Edition, I found a capacitor lying on my desk after reassembly.
                  I did not notice it detaching, so I am unsure of its original location on the PCB.

                  Procedure performed:
                  - Removed backplate
                  - Cleaned heatsink and PCB with isopropyl alcohol + soft ESD brush
                  - Reapplied thermal compound
                  - Reassembled card

                  Observed behavior after reassembly:
                  - GPU powers on and operates normally under...

                  Is it no harm to replace with capacitor without ripple current rating?
                  by chth96
                  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.
                  Rubycon YK DataSheet (b...

                  If I replace with inferior capacitor, Is it No harm to other IC components at all?
                  by chth96
                  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...

                  Should I replace polymer capacitor?
                  by chth96
                  a few days ago I finally purchased mser-100 v2 and I tested its abillity of measuring ESR value.
                  I found that It shows pretty accurate ESR value for electrolytic capacitor,But When I measure polymer capacitor of dreamcast game console,I found that one third of polymer capacitor's ESR value is more than twice the value of ESR meter table.(for example, I measured one polymer capacitor of 6.3v 100uf, It showed ESR value of 7.68)
                  Although my dreamcast now turns 20 years old but it still works. I occasionally have played game with it.
                  Is this ESR value of polymer capacitor correct?...

                  Found a blown capacitor - is it necessary to replace?
                  by expertreader
                  Hi all, Acer Nitro 5 - GH51M LA-K862P Rev 1A motherboard. I went through all the troubleshooting steps but couldnt find a short on any coils. By chance, ended up finding a blown capacitor PCZ49 which is suppose to be 2.2uF. I can see plenty of 2.2uF in the same +5VALW line which will all parallel up anyway - do you guys think it is critical for this cap to be replaced or i can get away without one?...
