Hi Chris,
These are also heavy-duty energy discharge caps, using a kraft
paper-foil dielectric system. The Aerovox PM series are all rated at 20%
voltage reversal, and no self-healing.
The low capacitance and dielectric system for your caps limit their use
to low pulse-rate, very high-voltage applications, such as flash X-ray,
Marx generators, exploding wire, or rock fragmentation work. The
dielectric system will be fairly lossy for lower-voltage oscillatory
applications, and the stored energy is limited for coin shrinking since
work-coil flashover limits maximum cap voltage to 20-25 kV.
You might be able to get more information by directly contacting the
folks at Aerovox. Unfortunately, many of their energy discharge caps are
custom designs. This often binds Aerovox to non-disclosure agreements
with their customers, preventing them from releasing even basic
capacitor specs...
Best wishes,
Bert

Okay, to get back on track to the topic, I have been following this with
interest.
I also have a pair of energy discharge caps that I have picked up last year
for a future project that I can't find any info either. Any info would be
appreciated.
Aerovox:
PM104YW003D04
3.110 uF and 3.364 uF
100,000VDC
15K Joules
They are in a stainless steel case.
A couple of pictures also if I made a typo...
