Notes on Failure[edit]

Just replacing only the exploded/leaking caps will not solve the problem. The other caps on the board will fail via leaking after the repair. Esp if only the leaking ones by the CPU are fixed, the original ones left by the CPU have a short remaining life if they are not bad already. Dell 270 systems are known for this, bad caps behind the CPU replaced, then, the AGP cap fails on the rebuilt Dell boards. Dell did write off millions to extend warranties and fix systems.


You really don't want to power up a suspect system with the case cover off. Swollen but not exploded caps are hot to the touch indicating a internal current leak. Think firecracker about to explode or vent. Looking at a system powered on with the case off is not safe. Acidic electrolyte and a can aimed at your eye for example. Just the spray from the top vent opening can 'paint' the case cover with electrolyte.


The section "Non-solid aluminum electrolytic capacitors" is only ancillarily related to the subject of this article. It's much more appropriate at the electrolytic capacitor article because it discusses electrolytic capacitors in general, not as they relate to this specific issue. -- Mikeblas (talk) 02:14, 28 April 2015 (UTC)

Against. The behavior of some manufacturers have created an unique criminal case within the history of electronic components. This substantiates an capacitor plague article to be useable as “stand alone” article. For that the explanation of the capacitor construction is important. --Elcap (talk) 11:14, 30 August 2015 (UTC)
Articles in Wikipedia don't need to be "stand alone" articles, as Wikipedia is not paper. The material here is redundant to (and already divergent to) the electrolytic article. The section in question is completely un-related to the capacitor formulation problem described by this article. -- Mikeblas (talk) 15:34, 3 November 2015 (UTC)
This proposal is stale, with support other than from the proposer. If anything, a merge to Aluminum electrolytic capacitor might have been more appropriate. For now, I'll switch to using a 'see also' template and someone can propose a new merge if there is interest. Klbrain (talk) 07:42, 6 September 2017 (UTC)

Harmless glue?[edit]

Quote: "A dark brown or black crust up the side of a capacitor is invariably glue, not electrolyte. The glue itself is harmless."

Is this really true? There are many reports of such glue becoming conductive with age and causing considerable damage as a consequence. — Preceding unsigned comment added by (talk) 20:52, 4 March 2018 (UTC)
