If it's of any worthwhile quality, the manufacturers data sheet will include that.

Most on resale don't have any accompanying datasheets.

I used one in my first attempt at a capacitive discharge spot welder, it lasted about 5 shots and then failed open. They're cheap for a reason.

For their dimensions and low voltage they can be made of film.
