Hello,

I'm trying to put multiple decoupling capacitos on my board mixing small and
large values in order to minimize the ESL and ESR.
What I'm wondering is when I use different types of dielectic for the
capacitors. For instance, I'm going to use 0.022uF X7R type and 470pF of
NPO type because NPO has the lowest ESR.

Does anybody know whether or not it's not a big deal in terms of mixed
dielectric material for high frequency decoupling?

Thanks,
TK
