::I hadn't thought about nominating the article for DYK, but you've made an intriguing suggestion here. Maybe the "hook" could be, "Did you know... that metallized film capacitors have a "self-healing" property which allows them to automatically clear away internal short-circuit faults, and to resume normal operation within fractions of a second?"  The article subsection pointed to had better be in tip-top condition, including good pictures and sufficient inline citations to verifiable references. The rest of the article should be at least in acceptable condition. 

 ::I followed the 2 existing refs from the "Self-healing of metallized film capacitors" section (one needs to be slightly updated already), and found more interesting info, including diagrams of "safety film" metallization patterns, which I had not seen before. Clearly, even this well-written subsection could still use improvement in references, and perhaps even in content. 

 ::If we really want to go for it, the article does need further finishing and polishing before we release it, since public release starts an automatic 5-day maximum limit on eligibility.  This rule implies that we should spend time in advance getting the chosen subsection(s) and the overall article into as good shape as possible, then release and nominate it, and be ready for a 5-day sprint to respond to any questions or suggestions for improvement from the panel of judges.  As to when there's a consensus that the article is ready for release, we ought to hear from , who did most of the original writing in German, as well as other editors working on the article.
