    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.

      Re: Capacitor help needed.

      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.

                              Help Needed: Reverse Polarity Issue on HP EliteBook 840 G4 – Where Do I Begin?
                              by Dev Goose
                              Hi everyone, I recently acquired an HP EliteBook 840 G4 (6050A2854301-MB-A01) that I'm hoping to bring back to life. I'm fairly new to laptop repairs but eager to learn and willing to put in the effort to understand and fix this. Any advice or guidance would mean a lot!


                              What Happened
                              The issue started when the laptop was accidentally plugged in with reverse polarity. Before this incident, the laptop would show a power/charging light whenever it was plugged in. However, now it's completely unresponsive—no lights, no power, nothing. I've been doing some research and understand                              ...

                              Asus FA507R no power, capacitor needed
                              by veedo
                              Hello
                              I've got an Asus laptop which received with no power, so I found that one capacitor been damaged. I don't have schematics for that board which is DANJMMB11A0 REV:A
                              Without that caps laptop is turning on fine so problem more likely is sorted but I would like to put back the correct one as it should be.
                              If any way could help with sorting out specification somehow, I just know that my meter shows 11,2uF but is it 50V or 10V ?? or any others.
                              See attached photo off the capacitor, maybe someone have same motherboard and can check it for me please.
                              ...

                              Hi people, I hope this is the correct spot to post this, I'm new to the forum.

                              I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.

                              I hope these photos make it clear which component I am referring to:
                              (yes, the soldering is a bit botched from removing the blown one, I know)

                              I have found the board schematic (attached), but there does not seem to be a boardview available. I have never...

                              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...

                              How can I test non-polarized capacitor?
                              by chth96
                              I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
                              I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm

                              And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
                              I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,...
