    Capacitor help needed.

    I am dealing with crown ce1000 amp. and I came across for strange capacitors. On PCB and cap there is no marked polarity. I know that is 47uF/10V but is this bipolar or regular electrolitic cap.

    Thanks for help.
    Regards, Sebastijan.

    polarity is indicated by the plastic base - it will match an outline on the board.

      The straight side is the +ve and the curved side is the -ve.

        Hello.
        Yes I know that. But what is confusing me is this that all other smd caps have + marked on PCB only this four not. And if I compare picture from link I am not shure that this is regular electrolitic cap.

          They do look to be bi-polar. What are the designator as printed on the board?

            Hello.
            Thanks for manual.
            O.k. C3 and C30 are clearly electrolytic caps but if I look C113 and C114 is different symbol like C3,30. So I think this could really be bipolar cap. I will order bipolar caps and try. Hope all will be o.k.

            Thanks, Sebastijan.

              The manual lists C113 and C114 as NP (non-polar). So these are Bipolar/Non-polar caps.
