Increase capacitor voltage rating by using multiple capacitors?
$begingroup$ @Majenko: The point is to reduce the high frequencies enough so that the active circuit in a voltage regulator can handle the remaining ones. Usually up to a few 10s of kHz is OK. For example, I often use some 950nH 600mOhm 200mA 0805 ferrites. With 22uF capacitance following these, you get one pole at 12 kHz from the R-C action, and …

Stacking SMD MLCC capacitors is perfectly fine electrically. If the capacitors don''t get too tall, it should also be fine mechanically, but vibrations might become a problem. Stacked capacitors can be put closer to the IC and therefore have less parasitic inductance than ones placed on individual footprints.

We utilize capacitor stacking to obtain passive voltage gain to compensate for the loss of these delay elements, thus permitting an increased number of interleaved paths and, hence, a higher delay. Furthermore, to reduce the RX noise figure (NF) penalty due to injecting the cancellation signal into the receiver, we introduce a novel low-noise ...
