    there are MANY other capacitors on that line. u dont need them or throw in any of suitable package.

    ^ could anyone provide a second opinion?

    Thanks for the quick response noname2024. I am assuming that 6.3*8 is referring to the dimensions in mm. However the component I am looking for is actually closer to 1mm in length and less in width. Is the capacitor you mentioned an equivalent replacement but in a different package?

    RTX 3080 FE Identifying capacitor

    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:

ID:	3519410 (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 really had to read schematics before, so I am a bit overwhelmed by it and haven't been able to figure out the capacitor values based on the schematic, but according to this video (https://youtu.be/THMukcOzB8g?si=vO7_O-d4__kqye8j&t=1311) the large capacitors next to it are output filtering capacitors. I hope someone is able to help me out here.

    Thanks in advance.

    P.S. The reason I found the burnt capacitor in the first place is that the gpu is having issues where it boots up ok, but under a little bit of load the fans spin up a lot and it heats up quite a bit, before eventually crashing. There is also a black burn mark on the gpu heatsink above above these capacitors. I am hoping replacing these capacitors fixes the issue, but let me know if that is unlikely to be the root cause.

    Need help – Identifying missing capacitor (HP CM 6050A2892401 MB A01)
    by woodboy971
    Hello everyone,
    I am a beginner in electronic board repair and I am looking for help with an HP motherboard: CM 6050A2892401 MB A01.

    Initially, the laptop would not power on. After troubleshooting and taking measurements, I found that a capacitor was shorted, which was preventing the system from starting. I removed this capacitor.

    After removing it, the PC now powers on for a few seconds and then shuts down. I believe this behavior is related to the missing capacitor, which is no longer performing its role in the circuit.

    My issue is that I cannot identify...

    Tantalum capacitor burning out
    by joetristan
    Hello,
    I’m using a 10 µF, 20 V tantalum capacitor as a decoupling capacitor across a 5 V supply. When I power the circuit, the capacitor burns out.

    At first, I assumed the tantalum capacitor was defective and replaced it, but the new one burned out as well when the circuit was powered.

    I then replaced the tantalum capacitor with a 10 µF, 63 V electrolytic capacitor. This time, the capacitor did not fail after powering the circuit.

    I do not understand why the tantalum capacitor burns up?

    Intel X520-DA2 NIC - Need help identifying C180 capacitor value
    by alhaddar
    Hi,

    I have an Intel X520-DA2 10G NIC (board revision E57333-003)
    where capacitor C180 fell off near FB4 area on the back of the card.

    I measured C180 on a working identical card in-circuit and got ~16.5µF reading.
    I estimated the actual value is 10µF 0402.

    Can anyone confirm the correct value of C180?
    Is it 10µF 0402 16V X5R?

    Thank you...

    ASUS Zenbook 13 Laptop UX333FN Need Help with SMD Capacitor Identification
    by jkucukov
    I have a ASUS Zenbook 13 UX333FN motherboard that I need to replace a SMD capacitor. This SMD capacitor is located on the back side of the motherboard and is really small (C0201), however I need to find the specs of the capacitor (Voltage rating and Capacitance).

    I was fortunate to find Boardview file for however all I was able to get from the file is the Capacitor reference designator (C6353), here is the information:
    How would I be able to get Voltage rating and Capacitance of the SMD Capacitor?

    Thanks,...
