New (surplus) 10KV 100nf (0.1ufd) Low ESR Capacitors Available
I now have in hand a small number of new (commercial) 100nf and
90nf reconstituted mica, low effective series resistance (ESR)
capacitors (0.1 and 0.09ufd) rated for 10KVDC.
These are caps that were intended for a very large laser discharge
system (the company closed). The caps are very impressive in
performance and small size. I've run them in my TC both DC and AC
from a 2parallel+2series (20kv) up to 5-in-series (50KVDC) arrangement
at 2KW continuous with no problems of any kind.
These puppies go for $250.00 each new in 100+ volume.
I have full detailed specs coming, but in summary:
Values: 0.100uFd and 0.090uFd +/-2% (non polarized)
Voltage: 10,000VDC (7,000VAC)
Datecode: 1997 and 1998
Temp: -55C to +125C
Continuous: 5.0A RMS (that's 35kw!)
Impulse: 4,000A peak
Size: 4.75" wide x 2.0" thick x 5.5" tall
Weight: ~3.6 lbs (1565gms)
Color: green and a few blue
Connector: 2ea Brass strips 3.25" long x .2" wide with 3ea 8/32 holes
Discharge time is extremely fast, in a 4-in-series circuit RSG driven
primary on the order of 100 to 200 microseconds (~5kHz).
These are available now at the following prices:
1 piece price: $50.00 each
3 or more: $40.00 each

Shipping charges need to be added in, so use the UPS estimate
from my zip code (95123) to yours for a 4 lb package (per capacitor).
