    Looking for the datasheet of this 5.6uF Elna capacitor

    I am looking for the datasheet of this (quite old) Elna capacitor. It is rated 5.6uF/50V, CE85° 0010 (S), the serie is CE-BP(LZ).



    Thank you.

    Is that picture from the web?
    The only info I found for ELNA BI-POLAR cap is RBD series;

      85' bypolar - nothing special
      not at 85'

        Given the size, it has a high ripple current rating for its capacitance and is also for horizontal deflection coupling.
        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.

          Just go with a metal film cap instead (PP, PE, etc.)
          You can thank me later.

            @Momaka: This is a good idea as this one measures a bit badly (around 2Ωs of E.S.R.) and quite high loss. Tipically this kind of capacitor as a E.S.R. inferior to 1Ω (measured other series took from CRTs) and very low loss (not higher than 0.8 on the average E.S.R. meter). It could be that it has aged. Howewer it is not clear if a single PP/PE is able to withstand 5-6A of ripple while this one should (though I will not use it as it measured badly).


            @japlytic: I think so. Howewer ELNA had another serie for this purpose and it is named with “H”. I've seen this different naming frequently even with other brands. Some are named “H” and some are named “LZ”. Sure they are both indicating high frequency capability but the differences are not clear at all.

            The suffix “LZ” is also used for several series low E.S.R. capacitors used in switching power supplies.

            The suffix “H” seems to be restricted to the purpose written by japlytic.


            The following one is the “H” variant. This is for sure for horizontal deflection coupling as it was listed as that onto an electronic store:




            Fitting the unproper capacitor in this circuit will result to failure of other components and the availability of replacements is quite scarce by itself. So it would be good (and also useful to other users) to discern which is which or if they are both suitable for the purpose.


            Hope that some of you guys can find a reference, a datasheet or a guide to markings used by producers.

              Good point.
              I didn't expect those old electorlytics (particularly the ones used on the H-deflection) to have such high ripple current ratings.

              That said, looks like you can still do it with PP caps.

              For example, looking at the Kemet C4AQ series of caps...
              https://cdn.badcaps-static.com/pdfs/...417b0c4c78.pdf
              ... a 500V, 5.6 uF cap (P/N: C4AQLBU4560A1WK) is good for up to 4 Amps RMS @ 10 KHz according to the datasheet. This is considerably lower than, say, Nichicon HA bipolar caps designed for H-deflection circuits:
              https://cdn.badcaps-static.com/pdfs/...cec55fa96a.pdf
              ... which can handle 7 Amps of ripple current for the same 50V, 5.6 uF cap.

              However, with the Kemet PP caps, if you move to the next higher rated DC voltage - i.e. 650V (P/N: C4AQCBU4560A1XJ) - then the ripple current jumps to 6 Amps RMS, which may be just enough. Only downside is the 650V PP cap will be bigger than the 500V one... and both will likely be much larger than the Elna BP electrolytic. On the other hand, at least you'll be getting excellent ESR with the PP caps: 15 mOhms or less. They are kind of pricey, though.
