    Is it ok to use a capacitor with a much higher ripple?

    Hi all

    I am trying to source some new caps for the power board on my LG TV. The one I am currently struggling to find a replacement for has the specs:
    Sam Young KMG 680uf 50V with a rated ripple current of 973. According to the catalogue these seem to be a general purpose capacitor and it is not clear why LG have used them on the power board.

    I like to use Panasonic capacitors but most of these have got a ripple voltage of 2-3 times the figure of the original capacitor. My preferred FR capacitors are 3160 while the FC ones are 2215. Would going from 973 to 3160 be way too over-kill and cause other problems? Are the FC series ok to use for a power supply board?

    Thanks

      higher ripple current is fine in my book .

          Replacing a GP cap with a low impedance, high ripple current rating cap is usually OK. Unless it was a GP cap in a circuit needing low impedance, etc., the original part would not have been a misuse.

              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...

              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...

              Trying to understand how to find best replacement cap for old parts.

              Recently I purchased a Tektronix TDS1012, a 20 years old product for cheap and I thought it could be a nice opportunity for playing (i.e. recapping) and learn something in the process.
              The power supply board is exactly the same from this post so I'll just steal it for now.

              I'm trying to find replacements for all those Lelon electrolytic caps, but then quickly...

              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,...

              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?...
