I have noticed there are different sized(SMT foot print size) ceramics capacitor with same voltage and capacitance ratings. I have been told that smaller the footprint, smaller the parasitic inductance and parasitic resistance a capacitor would have.. does this means I should select the smallest possible capacitor available? I'm gonna use this capacitors as bypass capacitors for MCUs. Available foot print sizes {C0402, C0603, C0805, C1206, C1812} capacitance needed - 100nf, 27pf.
and also, should I use a 1uf ceramic cap, parallel to 100nf bypass capacitors, just in case?
