Any good references for variable capacitor design?

    Good brands of run capacitor for house heat hump
    by cook
    Are there good brands for 'run capacitors' or 'start capacitors' that are used on electric motors or heat pump compressors? ... r are the good capacitor brands for electronics (power supplies, laptops, motherboards, etc.) also the good brands for run capacitors?
    Yeah I know this might be a novice question, but I just wanted to be sure. I did do a search on the forum but did not see this question asked before.

    Thanks

    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?

    gigabyte x870i aorus pro ice stuck on dram light, ddr5 power good voltage 0 when ram stick installed
    by Apoco_ lips
    I have a gigabyte x870i board I am attempting to repair. I have a working board as well to reference. The board is stuck on the dram light, wont post and I found the power good pin has 0 volts when powered on with a stick of ram installed. With out the ram it is 3.3v. Another weird issue with the board is when trying to use qflash to update the bios, the qflash light blinks for about 15 seconds then turns off for 30-45 seconds and then turns back on solid for about 3 minutes. My working reference board will flash the qflash led for about 15 seconds, turn off for a few seconds then turn back on...

    RTX 3080 FE Identifying capacitor
    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...

    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...
