    Elna Bad Cap?



    http://pg.photos.yahoo.com/ph/nsx29c...?.dir=/4d64scd
    hmmm... img attach not working.
    This Elna looks bulging. As far as i can see it's general purpose and surface mount so recap is impossible. This is very rare stuff. hmm.

    feedback welcome

    Ugh. Not Elna now!?

    Damnit! So much for me wanting to get Cerafines to replace the Scatronics in my speakers.

    It is possible to replace surface-mounted caps without the proper equipment... if you don't mind running the risk of tearing up the solder pads.

    BTW where did you find this cap?

      With an exacto knife and a moderatly hot fine tip chissel, that cap should be easy to replace.

        This cap is on a Elsa X1300 video card pci-e. Very recent stuff but according to date code. The elna cap is manufactured in 2004 which is very old stuff. I have no clue why it was used. I thought most computer stuff uses low esr stuff not general purpose.

        By the way, the system is running a zippy powersupply with chemicon ky caps. so i am confident that this must be some sort of manufacture defect or expired capacitor (not likely but i heard caps are good for 2yrs shelf life.)

          Even the best capacitors are not immune from failure...
          My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

            its no big deal to replace that cap.i replace sometimes 50 tiny ones at a time in old sony camcorders.
            10 minute job for me to replace that one and all others like it.

                It's probably a misapplication of a general-purpose, 85c cap instead of a low-ESR, 105c cap. Even Pannies and Rubies will fail quickly in such situations.

                There are probably no better caps than Elna R** for most small-signal audio use. For large caps in the Power Amp, Elna RJH works fine - but Panny FCs or Nichicon P* probably have a small edge for high dynamic-range performance. The differences are slight and highly subjective.

                Black Gates, Cerafines, etc. are probably wasted money, but if you've got a well-heeled customer who wants them, you might as well take the money first, and skip the common-sense explanations.

                  I consider Elna as good cap. They are long in business and have good Q/S.
                  And those SMD typs are very easy to desolder. Have replaced alot of them from a charging unit for Motorola GP900. Never needed something else than a soldering iron and something to pick up the hot cap.

                    Are there any datasheets available for Elna RJG capacitors?
                    by Ady2017
                    I have a 2007-era Panasonic VHS combo that is full of of Elna RJG capacitors. I am trying to test the capacitors to diagnose the machine and then select replacement capacitors but I can not find any datasheets for them. I did find a Elna catalogue from 2007-2008 but there is no mention of this capacitor series. Where these specially made for Panasonic and so not made available to the public? Any ideas what to find out what the ESR values should be without the datasheets? They are all between 10V and 50V and 47uF and 1800uF. None are leaking or bulged but I know that they need to be tested to be...

                    Elna capacitors - fake?
                    by Olkus
                    Hi,

                    I have capacitors like this one in the photo. There are differences between other Elna series, I attach foto of Elna RE3. On this green capacitors series is not specified! Fake?...

                    Does Elna Make any Cap Kits??
                    by Mark R
                    Been searching the universe internet. Can't seem to find a Cap kit with a Nice assortment of Elna caps. Low values and High Values. Anyone have knowledge in regards to this?

                    When the set came in it was dead. Fuse was open primary side and the power mosfet was shorted. So I ordered a new power supply. Now it turns on, only displays "Hitachi" and then power off red and blue led flashing.

                    I had to modify the 0ohm resistors in the led backlight of the new PS like the original power supply.
                    Is there any variants on 17IPS71 power supply's?
