    component Cap identify

    Hello,

    I have a doubt about these two caps and I need your help...


    47n = ? Capmeter measures 47nanoF

    v22= ? Capmeter measures 221nF ...

    I dont think its right.... At least the 2nd one...

    Regards, thanks in advance...

    u22 is probably 0.22uf
    aka 220nf

        probably not,
        i suspect the letter J relates to the voltage.

          Nothing printed on the side?
          It looks like EPCOS/TDK capacitor.
          Pictures of the whole board top and bottom sides?

            Re: component Cap identify

            J is the capacitance
            K is the voltage

              Nothing printed on side... Never seen any like these...
              I'll take some fotos of the board, tomorrow at work.
              And, yes I've followed the link you gave, and the symbol matches the one printed on the capacitor. I ll go browse deeper Thks

                  I recognize the logo as Epcos/TDK.
                  They all start with B32xxx part number for their film caps. Newer parts are laser marked instead of this mess.
                  I believe it is a 0.22uF 1,250VDC polypropylene film cap. These caps rarely fail, they are self-healing and pretty tough.

                  u22 = 0.22uF or 220nF
                  P654 = B32654 series
                  1k25 = 1,250VDC
                  J=+/5% tolerance

                  Part number might be: B32654A7224

                  Check the dimensions/size, but it's high-voltage low leakage, high frequency cap for your analyzer.

                    DVR HIKVISION DS-7208HWI-E1/A BOARD DS-80104 REV 2.2 help identify burnt components
                    by thesame
                    Hy guys , i have a DVR board DS-80104 REV 2.2 that was powered wrong, i have some smds on the board that are blown and i can't identify them , maybe if someone has this board somehow and we can identify the smds', i have searched online and i can't find a schematic.
                    The smds are SOT-23-6 , one of them i think it has the marking ADJF since i found another one on the board with this marking , but the other one it seems that it starts with AG or it looks like. I would really apreciate if someone could help me identify those IC's .

                    How can I identify varistor which have been blew up?
                    by chth96
                    I mistakely pluged 100v japanese retro game console to 220v outlet.
                    So It seems that glass fuse and varistor have been blew up.
                    I can identify that voltage and ampere value of glass fuse(250V LF 1.6A),but It is impossible to identify varistor type in my sega saturn PSU(YAMAHA 35M07U XR258)
                    Is there any way to identify varistor type in my sega saturn PSU?
                    Any reply would be appreciated.


                    EDIT:
                    It seems that I finally found out what type this black varistor is. It is Panasonic ERZV05D221 “ZNR” Transient/Surge Absorbers (Type D) Varistor Voltage...

                    by sdogs
                    I have a macbook pro 14.1 A2442 that has had contact with liquid, the affected area is the one near the touch id connector (see image). I carefully cleaned the affected area but the UT600 chip (LM3638A0) seems to be in poor condition and probably needs to be replaced.
                    I searched online and found the replacement but it is indicated as a spare part for iphone 6 and 6 plus and at this point I had a doubt, does this chip have some type of programming?
                    Forgive the question, I'm just an enthusiast but I had this doubt and before ordering the spare part I wanted to be sure I wasn't doing...
