    Is this capacitor any good???

    Hi all. Just checking to make sure if this cap is good bad ugly.
    I believe it is supposed to be .047 with a 10% tolerance. I just want to make sure Im reading this correctly.
    44.89nF or .044mF
    on the schematic, it is c4
    So, it looks like it is just barely ok. what you guys think please.
    Thank you

    Yes it is good
    473 = 47nF = 0.047µf

      The cap looks fine. C4 in series with R13 2k2 1/2W is likely a snubber cap?

        C4/R13 are used to couple the A/C line for a clock reference to ic3

          I don't see that in OP's pics, you must have the info from another post?
          400V cap is more common for mains or snubbing.

              Good brands of run capacitor for house heat hump
              by cook
              Are there good brands for 'run capacitors' or 'start capacitors' that are used on electric motors or heat pump compressors? ... r are the good capacitor brands for electronics (power supplies, laptops, motherboards, etc.) also the good brands for run capacitors?
              Yeah I know this might be a novice question, but I just wanted to be sure. I did do a search on the forum but did not see this question asked before.

              Thanks

              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...

              How can I test non-polarized capacitor?
              by chth96
              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.
              I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,...

              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...
