Bert,

You may very well be right. I asked the seller about their application
and he said that he thoguht that they come out of an RF power supply
and that he thought that they would be suitable for energy storage or
energy discharge application. Speaking of relatively small physical
size, the Maxwell 37667s are really quite small for their cap/voltage
rating but yet they seem to be very suitable for coiling purposes (1000
pps and high pk currents).
