Nope!  I can't find what you're talking about.  There's something wrong when someone have to provide a tutorial on how to navigate their website.  Somebody should be thinking "maybe our website isn't that easy to use."

Anyway, never mind.  I'll try Digi-Key , Mouser, etc.

Thanks Jim.

They are there -- you have to look under the EMC products, not inductive 
products. Same thing, but the inductive parts are tested for inductance 
at low frequencies while the EMC parts are tested for impedance at 
higher frequencies.  See Appendix One of the RFI tutorial for Fair-Rite 
part numbers and a list of known good sources.  Off the top of my head, 
Allied, Newark, Digikey, Kreiger, Lodestone Pacific come to mind.  It 
pays to shop around, and to buy in quantity, combining quantities with 
your ham neighbors and clubs.
