    Has anyone actually made a capacitor?

    I don't mean one of those jar ones, or the ones where you make a massive thing using cling-film and it ends up storing 1pF or something. I mean an actual canister shaped one. Now I know these usually require big machines and great precision but I was wondering if anyone made one as proof of concept.

    Come on, even a homemade one is better than a GSC.

          That wasn't proper science though, that was just bellendery...

              The manufacturers state the basic science behind it... The ridges in the aluminium relate to the voltage, and the electrolyte defines the characteristics... But they don't give you any specifics, so I imagine that it would take a good bit of reverse-engineering to make one.

                  It'd be quite cool to make a basic one in the same shape (but bigger) and refine it from there. But I think the main problem would be longevity from impurities in the metal as well as dust introduced in the inevitably non-clean room environment.

                      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...

                      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?...
