Note also that, to a variable extent, depending on dielectric, phase of
moon, dead fish count etc, ceramic capacitors can exhibit a  response to an
applied voltage step that causes them to "ring" to well above supply voltag=
e
in some cases. So eg applying a 5V power supply switch on step may result i=
n
a ringing response of , say, 10V. Susceptible equipment may be destroyed by
this effect.
