    Can you help me identify this capacitor?

    This is on a Samsung TV that stopped working. Looks like I should be able to just replace this cap:

    Can you tell me what specs I need to look for? If you could link me to a specific product, that would be awesome.

    Any other info about replacing the cap would be great. I replaced a cap on a powered speaker. The soldering went well. But I'm still pretty novice with this stuff. So, I might not know something basic. Like, anything I need to do to avoid getting shocked? I plan on leaving it unplugged for hours before I remove the pin connections and remove the board.

    Are there any places besides Radio Shack that I could pick up this cap?

    Pretty sure I ordered my last caps from DigiKey, so I guess I'll do that if there are no stores that sell them.

    You can use Panasonic FM series or FR series for the replacement, just get the one that the dimension (Dia and height) will fit the board. FM and FR are what I use for repair, I get them from DIGIKEY, you should at least replace ALL those cap in the secondary side.
    Radioshack sells general purpose cap, you need 105c LOW ESR type.

      There is no RadioShack near me. I don't know how to be sure I'm getting the correct size online.

            If you googled panasonic FR or FM you'd just about be there including links for mouser or digikey.

            Aluminium electrolytic

            http://www.digikey.com/catalog/en/pa...fr-series/3611

            http://www.digikey.com/catalog/en/pa...fm-series/3610

            Things to watch for, physical size, voltage, temp. You can go up in voltage provided it'll still fit .

            I think there were some models where 10V caps were in and may have been borderline, often a 16V will fit.

            These are polarised devices so pay attention to the negative and where it goes. Traditionally the white band and the lead that is cut shorter is negative, on the boards a white marker or white hatched area is negative but check it out as you disassemble or take a photo or 2 before you start.

            It's rare but every now and then I've read of someone who rips all the caps out and then realises they're all different values and ratings ending up not knowing what went where.

              There are a lot of options in those links. I don't see sizes listed, and I'm still not sure what sizes I would need anyway.

              I'm wondering if this would be better for me:

                Well, a friend of my parents had an extra 25V 1000uF 105ยบ cap. I switched it out and the TV works!

                If it fails again soon, I'll replace all the caps.

                  Remove capacitor without damaging the board
                  by GoodCapacitor
                  I have an old Mikrotik board with one bulging capacitor. It still works, but the cap doesn't look healthy.

                  I have tried replacing it, however it seems to ignore my soldering iron like it's a toothpick. I do suspect an industrial-strength lead used during manufacturing.

                  How do I remove it without damaging the PCB and (more importantly) surrounding components which might be more temperature-sensitive.

                  Help to identify a laptop mainboard SMD capacitor LA-9982P
                  by BlackBurn
                  Hello everyone,

                  I have an Dell Inspiron 15 3537 laptop mainboard (LA-9982P Rev. 3.0 (A02)) with a blown SMD capacitor as shown in the attached images. However, there is no printed specifications near the capacitor or a codename for the capacitor to identify the specification of the capacitor to replace it. I wonder how to identify the capacitor since the mainboard schematics are also useless as the capacitors are not named on the board. Any help would be highly appreciated.

                  Thank You. Stay Safe.

                  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.
