    G Luxon 25v 10uf 105C capacitor

    This is a really tiny capacitor I took out of a motherboard this morning so I could see what it was as I suspect it's faulty and why I'm having issues with booting. With the ESR meter it shows a reading of about 8 and there is another identical cap not too far from it which measures about 2.

    Tried looking on the net to find out what the normal ESR should be for this cap. How do I find out? TIA

      Re: G Luxon 25v 10uf 105C capacitor

      With one at 8 and the other at 2 I'd say it's bad.

      Normal would depend on what series of G-Luxon it is and what size.
      An LZ 25v 10uf 4x7mm is 2.5
      An LZ 25v 10uf 5x11mm is 0.55
      An LV 25v 10uf 5x5.4mm is 1.2
      Any General Purpose series would be more than those.

      But 2 -> 8 on same-same.
      Yep... It's no good.

          RTX 3080 FE Identifying capacitor
          by Prolog
          Hi people, I hope this is the correct spot to post this, I'm new to the forum.

          I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.

          I hope these photos make it clear which component I am referring to:
          (yes, the soldering is a bit botched from removing the blown one, I know)

          I have found the board schematic (attached), but there does not seem to be a boardview available. I have never...

          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...

          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.

          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?...

          Samsung C32HG70 - Blown Ceramic Capacitor (CP813)
          by NuclearSpartan
          Hi everyone,

          I'm new to this, so I apologize for not providing enough details. Is there anything else I need to mention? I'm trying to learn more about electronic/board repairs and hopefully fix my own.

          The only visible issue on my board is one capacitor, CP813, which appears to be labeled R 221k 2kV (possibly obsolete to B 221k 2kV now). My monitor hadn't shown any prior issues, although it is a few years old. Just before the capacitor popped, there was a high-pitched squeal for 2–3 seconds.

          I don't see any other visible damage anywhere else on the board....
