A question for you...  Looking at the "Impedance vs. Frequency vs. Turn 
count" graph at:


It looks like these new cores only have two or three K of impedance with 
  five turns...  Am I interpreting this correctly?

If so, then using two of them with five turns becomes the standard if I 
want more than five K impedance?  Is that true?

73s and thanks,
