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?

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...

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...

Hi,

I had a MXM graphic card type Nvidia K1000m from laptop HP8570w which had a broken capacitor.

The ceramic capacitor seems was broken and makes a short circiut. The laptop goes off because of the short-circuit. But it seems currently that only the capacitor C55 was broken on the graphcic card.
Because after I have desoldered it, the laptop runs with the card. But currently without this capacitor.
So to have full functionality and no instabilities I want to replace it with a new one.

So I need to know the value and voltage of C55 to replace...

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!...
