Thanks Kooler, this helps.  I may want to use the TS3001 to pulse a ferrite JT.

5.2khz-90khz is the only freq to use in it.. but that would be good enough .. there less than 2 dollars a peice
i like the one resistor to set freq.. here for others to see..  datasheet  http://pdf1.alldatasheet.com/datasheet-pdf/view/455936/TOUCHSTONE/TS3001.html
