    it's a motor run cap
    3uf 5%
    never seen multiple voltages on one before, common size is 450v

        Re: need suggestions replacing large capacitor

        Actually I was more hoping for a quality replacement because we've replaced this MANY times and they just keep breaking

        Unlike usual capacitors on psu im not sure what to search for

            "Unlike usual capacitors on psu im not sure what to search for" Motor run capacitor.
            I do not know what you have available in your country.
            What kind of unit is it used in, Voltage? It is only 3uF so must be a small motor.

              Those different voltages seem to indicate shorter hours of operation as the voltage increases so I'd try to find a higher voltage cap so that the hours of operation are near or at the lowest rating. Did I read 400V / 1000hours, 500V / 120 hours?

                Re: need suggestions replacing large capacitor

                no, 400v 10,000 hours,
                500v 1000 hours

                that's still nothing when you do the division.
                1000/24(hours in a day) = about 40days!!!!

                  an air conditioner compressor unit, and they charge me about $40 for each replacement

                  its quite costly

                  its been at least 3 times now theyve been replaced unless.... they are taking me for a ride.

                    Majority PETERHOUSE GRADUATE Internet Radio (Auna Silver Star) - Stuck at boot "Welcome" Screen
                    by praveenramavath
                    Hello All,

                    I have an issue with my Majority PETERHOUSE GRADUATE Internet Radio, it keeps rebooting at the boot logo Welcome screen. I have an another forum active in other website but due to lack of response I am posting the same here. I am positing a link below that has pictures including all the troubleshooting I have tried, appreciate if someone can take a look and give me any suggestions.

                    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.
