    What capacitor

    I have reballed the GPU and have 3 blown capacitors on a hp touchsmart with ratings 5v 820uf. 105C
    I have no capacitors in stock with that rating. Before I waste my time would 6.3v 1000uf do the job or can someone recommend a more apt set?

      Re: What capacitor

      820uf must be the same, voltage can be a bit higher, so a 6.3v 820uf or 10v 820uf is ok.

      6.3v 1000uf is not ok.

          5v is not a standard voltage rating. It could be 25v and you just don't see the 2.

          The standard values are 2.5v 4v 6.3v 10v 16v 25v etc

          Low ESR 1000uF would be fine I guess, 6.3v would also work if you're absolutely sure that capacitor is 5v or less.
          Maybe 5v is some series code or it's actually 25v and you simply don't see the voltage rating due to capacitor being very small?

          It would help if you could post some pictures.

              fixed that for you.

                      You should use polymer capacitor, 560-680uF.

                      If you don't have polymer, you can use electrolytic but should use capacitors rated for higher voltage so that the ESR value would be closer to the value of the original capacitor. And up to 1000uF would probably be fine.

                      CPC sells them in UK and relatively cheap, here's what I'd recommend :

                              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.

                              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.

                              (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...

                              Motor run capacitor physical size vs voltage rating & measurements?
                              by Per Hansson
                              (TL;DR skip the first paragraph)
                              I encountered my first dead motor run capacitor at a customer this week.
                              For some fields I guess it is a very common occurrence but the usual way for industrial machines here is to use 3-phase motors.
                              (Unless a servo motor makes more sense that is).
                              But for some reason this 3-phase machine uses a 1-phase motor for its liquid coolant pump.
                              The pump would run but sometimes trip the 10A breaker.
                              I monitored it starting and stopping for over an hour until it finally stopped in a specific spot between its windings:
                              Then it could...

                              Explanation of capacitor rating
                              by Adenitz
                              Hello,
                              I'm reading an article about the "capacitor plaque" in early 2000s and I have found one sentence I cannot understand.
                              The normal lifespan of a non-solid electrolytic capacitor of consumer quality, typically rated at 2000 h/85 °C and operating at 40 °C, is roughly 6 years. It can be more than 10 years for a 1000 h/105 °C capacitor operating at 40 °C.

                              What this 2000h or 1000h means? Why 1000h capacitors have longer life span?

                              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...
