Other things have pulled me away from my many caps primary cap project but
I wanted to say that those Panasonic poly caps have performed with
excellence for me!  They run cold and have very high margin.   I think
mixing them together to get a desired value will provide a very good and
reliable device!  The 630 volt ones I use break at around 2400 volts.  When
I take them apart (I am a failure analysis engineer), their internal
construction is very good.  I would not hesitate using them for any TC use.
