    Help to identify SMD capacitor markings.

    I need to replace a surface mount capacitor but not sure what the markings mean. Surface mount became popular after I finished electronics at a vocational school years ago. (I know, I've practically given away my age) Looks like it was just a bad solder connection, but the capacitor is ruined.

    These are the markings:



    Any help would be appreciated.

      I think it is an tantalum capacitor, so i would guess it is 10uF, 35V (that is the usual notation).
      But if you want to be sure, you have to figure out the manufacturer and lock at the data sheet.

          There's no other markings to determine manufacturer. It was in an external enclosure made by Formac. the enclosure doesn't even say the model type.

          It says made in Germany.

              Well, probably an older part from AVX. At least the black / white labelling is used by them still today at some of their high reliability tantalum's.
              But usually they print the series on it too. May be the M8 is the series, but then it is probably an older one.

                  I'll see if I can search them out, unless you have a link? The device the cap went to was manufactured in 2001, so it's quite possible it is an older series. I just have no clue how to look up the specs. I don't know how many places would go back to 2001 in specs though.

                      I would try www.avx.com, but i think you will not get the old data sheet there. Their site is a little unsorted.

                          I never did get an answer from the site. I sent a few messages with no reply. Still no luck in figuring it out. I may have to unsolder an existing one and hopefully my tester will be able to properly read it.

                              its just a standard sm tantalum
                              hit the digikey site and you will find them.
                              if it were mine and i didnt have that cap on the shelf i would try a low esr lytic.

                                  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...

                                  Need replacement advice for surface mount electrolytic capacitor
                                  by beogeek
                                  Hi all,

                                  I have a faulty monitor, the surface mount electrolytic capacitor 33uF 100V needs to be replaced, now I can't seem to source them locally, so my question is can I replace it with a through-hole electrolytic capacitor of the same value? Or has someone got a better suggestion?
