Meaning of electrolytic capacitor "CE" markings
Some electrolytic capacitors, especially older ones have markings of "CE" on them. This is short for "Condensateur Électrolytique", the French acronym for Electrolytic Capacitor.

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... -
there a risk of this aluminum electrolytic capacitor of electronic device long term storage opening and leaking acid and corroding the PCB board?

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... -
Hi all,
I have a faulty monitor, the surface mount electrolytic capacitor 33uF 100V needs to be replaced, now I can't seem to source them locally
, so my question is can I replace it with a through-hole electrolytic capacitor of the same value? Or has someone got a better suggestion?

Anyone had a solid polymer capacitor fail for whatever reason?
How do they fail? Do they explode, go open, short out, ?
How about for different reasons: forcing excessive ripple current, overheating, voltage too high, reverse voltage?
Just wondering about the causes for a potential shorted solid polymer capacitor... trying to debug a board that has a ~4Ω "short" on a track... it may or may not be a capacitor but was wondering what if it were...
