    Hi to all.
    How can you tell if a cap is a low ESR type.
    I have a lot of electrolytics around , but I am not sure if
    any of them are low ESR types.
    Is there a paticular marking that a low esr cap would have.
    Cheers.

    ** Low ESR is all in the mind of the particular cap user.

    Low relative to what ???



    ** Then it don't matter one tiny **** to you.


    ** No.

  3. You measure it and/or read the data sheet.
    It depends on what ESR you need.
    A "low ESR" cap may not be low enough for your given application, and
    alternatively a "normal" cap may already have low enough ESR for your
    application.
    There is no standard symbol or marking.
    Some are marked in some way to make make it fairly obvious, but many
    aren't.

    Thanks for YOUR reply.
    The caps are used in an SMPS. I have another post about that in this
    group.
    The person I got them from said they were a low esr type ,but I was
    wondering
    how I could tell , apart from measuring them with an ESR meter.
    Pity there are no markings to say.
    Thanks

    BEWARE: googlegroups cretin on loose !!!


    ** Shame you did not actually read it - fuckhead.



    ** Then look up the maker's data sheet - you IDIOT !!

    You have the damn caps - right ????

    Then you have the maker's brand name and the type codes / numbers.



    ** Course there are - Fuckwit.

    The codes are printed right on the damn cap !!!!

    Buy yourself one of these:
    http://members.ozemail.com.au/~bobpar/esrmeter.htm
    Then you will know for sure whether your capacitors are low ESR. I have one
    (DSE Mk2) and it is good.
