There is a type of capacitor called a paper or oiled paper capacitor.
Many non-electrolytic caps of 250 V or more, and of large values,
are made this way. They have quite low series inductance, which
is the desired quality. A mylar or polypropylene film capacitor
would also work fine, but cost a lot more.
