    Capacitor detached from PCB – RTX 2070 Super Founders Edition
    by MORETTIGIAN
    Title:
    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...

    Is it possible to test small ceramic disc capacitor with analogue meter?
    by chth96
    I read EBOOK of Testing Electronic Component and found that

    "In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
    Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
    It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."

    Is it really possible to test small ceramic disc capacitor with analogue...

    Samsung C32HG70 - Blown Ceramic Capacitor (CP813)
    by NuclearSpartan
    Hi everyone,

    I'm new to this, so I apologize for not providing enough details. Is there anything else I need to mention? I'm trying to learn more about electronic/board repairs and hopefully fix my own.

    The only visible issue on my board is one capacitor, CP813, which appears to be labeled R 221k 2kV (possibly obsolete to B 221k 2kV now). My monitor hadn't shown any prior issues, although it is a few years old. Just before the capacitor popped, there was a high-pitched squeal for 2–3 seconds.

    I don't see any other visible damage anywhere else on the board....

    is there a brand of smd ceramic capacitor use in iphones? or they are generics

    identify capacitor for MacBook Pro with rare logic board 820-02037-06
    by devsigner
    Hi

    While messing around with my MacBook Pro, I stupidly pinged off a very small surface mounted component that I’m now trying to identify.
    resistance tests show a rising resistance value, indicating a capacitor.

    The laptop boots up and runs, however I'm choosing not to use it until I get it fixed.

    i can’t see any markings on the capacitor at 10x magnification using a professional jewler's loop.

    It seems like there's some damage to the capacitor - one side doesn't have "shiny bits" - can you tell I don't do this for a living!...
