I'd say don't risk it. According to this datasheet, these caps "are
not intended for continuous pulse applications", nor "for series
impedance applications":

This datasheet doesn't have the above disclaimers:
http://www.datasheetcatalog.org/data...ay/mkp3384.pdf

However, page 6 has a voltage versus frequency graph which shows that
the maximum RMS AC voltage of 300V starts dropping from about 300Hz.
At just above 10kHz the max voltage rating is only 10V, at 1kHz it is
about 100V.
