Lee:
Thanks for your comment. That's what I'm thinking of. It seems that the
inductance coming from vias/stubs associated with cap is the major contributor
of ESL, compared with the portion from cap packaging.
BTW, when you say "0306" you mean "0603", right ? Because "0306" sounds like
one type of LICC, where they align terminals along the long side of cap to
increase mutual coupling between terminals.

Perry
