    Need help identifying capacitor

    I accidently knocked a surface mount capacitor off a nVidia geForce4 MX agp video card. It is the same as this capacitor, which is located elsewhere on the same video card. The numbers on the capacitor are 122-100-25Z.

    Can anyone translate these numbers? Thanks for any help.

          I thought that's what it might be, but the first number (122) confused me, as did the Z after the 25. And I'm pretty new to this type of stuff. Thanks for the help!

                      Thanks for the reply. According to the information to which you refer, the cap would be 10uf.

                      The first two digits of the "100" are significant, and the third digit represents how many zeros follow it. So, 100 represents 10 followed by no zeros, which is then read as just 10uf. (101 would be 10 followed by 1 zero, or read as 100uf.)

                      The 25Z is the voltage followed by the series number.

                      I guess the 122 is a date code, although this company uses a letter and number combination for that now. Maybe 12th month of 2002? That would be about the right time frame for this video card.

                      Does this sound reasonable?

                          I discovered the video card works without the missing capacitor.

                          Well, I guess I'll pick up both a 10uf and a 100uf and then flip a coin.

                              by Prolog
                              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...

                              Capacitor detached from PCB – RTX 2070 Super Founders Edition

                              Capacitor detached from PCB – RTX 2070 Super Founders Edition

                              Description:
                              During maintenance on an RTX 2070 SUPER Founders Edition, I found a capacitor lying on my desk after reassembly.
                              I did not notice it detaching, so I am unsure of its original location on the PCB.

                              Procedure performed:
                              - Removed backplate
                              - Cleaned heatsink and PCB with isopropyl alcohol + soft ESD brush
                              - Reapplied thermal compound
                              - Reassembled card

                              Observed behavior after reassembly:
                              - GPU powers on and operates normally under...

                              Help identifying missing smd capacitor for HP elitebook 840 g3
                              by Ambro
                              In an unfortunate mishap while attempting to read from the bios chip, one of the smd capacitors took flight and disappeared.

                              I'm not sure how crucial this smd capacitor is, but it was a brown possibly ceramic one with no notable markings on it anywhere.

                              I've attached a picture of where it's located on the board.



                              Does anyone have an HP elitebook 840 g3 who might be able to aid me identifying this component. I'm not sure how crucial it is, but didn't want to risk it.

                              Thank you for any help you can provide....

                              Need Help Identifying Capacitor On Kar-Tech Versa Remote
                              by grimacelord
                              Hello,

                              I have sort of a weird one here. This is the circuit board for a Kar-Tech VERSA remote. It's a wireless transmitter for crane and other heavy equipment.

                              One of the capacitors have blown and I need help finding a replacement. The capacitors are 11.4mm x 6.6mm in size and the only imprint on them is "200mΩF", which I am assuming means 200 microfarads. There is no other markings on them. I have tried doing some searching on digikey and mouser, but I can't seem to find anything like this on there or I am inputting the wrong search parameters....

                              PS5 Edm-010 No Power - Help identifying missing capacitor
                              by krob80
                              Hey everyone. I recently acquired a PS5 that is not turning on (no beep/power). PSU is good and there is no shorting on the 12V rail.
                              It came with a Gen3 SSD installed so I feel that things went down hill for the previous owner when it was installed. F7003 was blown but there was nothing shorting to ground. I replaced the fuse but still no power (new fuse is still good for now).
                              When connecting it to a bench power supply, it only pulls 10 mA (doesn't spike when first connected).
                              I noticed that there are a couple capacitors missing from the Vcore power regulator (pictures attached)....
