Yes, sorry, it's a bad choice of words on my part. That table is for the "operating voltage rating between conducting copper elements on external pcb layers" (item #2.4.2, table #8), and the breakdown voltage will be even more high. Also it says that maximum recommended voltage is 2300V for FR-4 (glass-fibre laminate, textolite) and 1800V for FR-2 (paper-based laminate, paxolin).kb1gtt wrote:Break down voltage and creepage / clearance distances are 2 different things. ... I am not familiar with it or the context of this table.
Of course it's just for your information - to "broaden the mind", in a manner of speaking...
