@RyanGriggs The capacitance loss of some ceramics is really problematic if you are relying on them for ripple reduction. The only countermeasure is more capacitance. If the resonance is 13 kHz (correct) then you want the RC phase shift to be significant at this frequency. If you don't use the little pull-down menu on the left side of a new comment you can't directly reply to it and I don't get a notification hence, the lateness.
