Terry,

Commercial pulse caps aren't "fragile", they simply need to be properly
speced for the intended use and then operated within those specs. I have
certainly never had a commercial cap fail from "overcurrent" as your
recent MMC postings seemed to indicate. Actually I've had only one
commercial cap fail in 15 years and that was due to a manufacturing
defect in one section. The company built me a new one for free even
though the warranty period had run out!

MMCs are OK for "playing", commercial caps are for more serious work!
