One of the things I've been curious about for a while is the advantage of
using larger footprint devices (maybe 1206 vs. 0603) in the same capacitance
value. Logic would _seem_ to suggest that the smaller package must be
taller and therefore have a greater current vs. height function. Since they
have the same 2D length to width, it would seem the larger part would be
preferred. I don't have the equipment to measure this, so any thoughts
would be appreciated.

Subject: [SI-LIST] Importance of Package Height
Not too long ago I ran across several articles - EDN?, Electronic Design,
PCB Magazine -- on the importance of IC height above the circuit board, but
have not been able to find them. Can anybody help me locate them?
