Maximum capacity of film capacitors

Explaining Capacitors and the Different Types | DigiKey

Many film type capacitors will specify a maximum rate of voltage change (dV/dt) that is to be applied across the capacitor. This is tantamount to specifying a peak current through the device since I(t)=C*dV/dt, though voltages are typically more convenient to measure than currents.
