Don't know but from looking at the picture:
http://www.allelectronics-dot-com/cgi-bin/category.cgi?category=search&item=MP-2
0&type=store
there is zero information about the ESR or long-term current carrying
characteristics. (overheating)

The info that _is_ given is that this is good for "snubbing" - ie: dealing
with occasional transients.

#1)  - something that isn't known but is $22 cheaper (but if it blows, you
are out $176 plus shipping)
#1a) - is not known to work reliably, has zero community support, the
savings is only 10% or so,
        these caps were probably around when the Geek Group did the MMC
configuration and
        they probably looked at them and didn't choose them.

#2)  - something that works
#2a) - something that is supported by the community

I would go for #2...

Could this be used to make a large MMC style capacitor?  Take 22 of them in
series which gives 1000v*22=22kv
2uf/22=.091uf
22 caps
$8 each*22=$176

copared to a geek MMC of compareble size....

2000v*11=22kv
.15uf/11=.0136uf per string
.0136uf*6 strings= .0816uf
11 caps*6 strings=66 caps
$3*66 caps=198

Thought it was worth asking, maybe useful for MOT of Pole pig cap.
