The mainline distributors (Allied, Newark, Mouser, etc.) have excellent selection of Fair-Rite and other cores. Admittedly to a neophyte the equivalence of Fair-Rite or Laird part numbers to an Amidon-style number may not be evident. Clifton labs has excellent webpages of examples and is also a good way to find the cores sizes and materials commonly stocked at the mainline distributors using the manufacturer's part number (often with cross-ref to Amidon style number as a strong hint!) Recently some here expressed concern that the mini-circuits part may saturate with medium DC currents. Of course if you are doing a SMT production run you don't want to use bigger cores than necessary and most of the mini-circuits parts tend to be physically very tiny to meet this market. But if you wind your own on bigger cores this is a non-issue.
