Hey Paul,
They have a 20% voltage reversal as I recall. 2 In series gives us 70KV
20%
gives us a usable >14KV.
This has been on the list many times!

I use 2 in series for my 4" coil just fine at ~120PPS

I don't mean to hurt your sales effort or anything but I have owned
several
of the Maxwell caps and discovered some problems with using them with
Tesla
Coils.
They have a relatively low duty cycle and there have been at least a
couple
of coilers who have suffered catastrphic failures using these caps. You
can
search the archives because there was a thread that discussed this at
length
about 3, maybe 4 years back. One person, I can not remember his name,
unfortunately, who had his fail and he went to the trouble of
disassembling
it and taking photos of what had been destroyed.
If I remember correctly, his solution was to use 2 of them in series to
get
.015uF and 70kV to use with a 15kV 30mA neon sign transformer. I can not
remember any other of the details now. I will try to find it in the
archive
and pass along what I find. I thought everyone should be aware of this. I
seem to remember also that Mr. D.C. Cox was involved in that discussion,
if
he cares to comment. That is if I'm not wrong, AGAIN! :-) My memory is
pretty foggy these days but I am fairly certain he at least made some
comments during that discussion.
This is not to knock these caps at all. I recently sold two of them on
eBay
myself. Apparently, they are a perfect fit for high voltage flash
photography and Kirlian photography as this was the application the buyer
was using them for. They are definitely pulse discharge caps and good to
35kV. It is only the duty cycle that I am aware of that presents any
problems, which leads me to wonder why using 2 of them in series helped??
