Nothing wrong with it, but the common mode impedance curve is strongly 
influenced by the physical size of the core, the transmission line, and the 
winding details. If you're prepared to wind some designs and measure them, 
be my guest. The performance of my designs is documented in the pdf on my 
website. I've seen no specifications or measured data for any of the DXE 
products, and the DXE I've measured myself have not been impressive.
