Capacitor selection for filtering of low level signal
$begingroup$ But when sampling at 3x bandwidth, steep input filters are a must, and they are not practical for low frequencies unless you''re designing a high order switched capacitor filter within an IC. For the 300Hz sampling case, you''d need a filter that goes from passband to bandstop between 100Hz and 150Hz. The behavior of that filter …

What happens if I connect a low voltage rated capacitor to a high voltage?
For a capacitor, one of the limits is keeping the voltage low enough that the capacitor dielectric stays intact.
