1. As ESR goes down, the troughs get deeper and the peaks
get higher.
2. The minimum impedance value is not necessarily ESR
(or ESR/n, where n is the number of identical parallel capacitors);
it can be lower than that!
3. The impedance minimums are not necessarily at the self
resonant points of the bypass capacitors.
4. For a given number of capacitors, better results can be
obtained from more capacitor values, with moderate
ESRs, spread over a range than with with a smaller set of
capacitor values, with very low ESRs, at even wellchosen
specific self resonant frequencies.
