Critical information for those that aren't aware: MLCC capacitance decreases with applied DC voltage, like, a whole fucking lot. [1]
Those 10uF/100V/X7R/1210 capacitors you love for your space constrained designs might only be 1uF at 48V. And it gets worse when choosing smaller package sizes.
This caught me completely off-guard. I've always thought an MLCC with a reasonable Dielectric at a given Capacitance would perform at least as well as an Electrolytic or Tantalum (minus fire hazards).
