One is not restricted to Fair Rite; Steward (Laird) has its own equivalent
formulations.

For example, their part LFB127079-000 is 12.7 mm across and 7 mm "long",
with 2-turn impedance of  >80 ohms from about 1.5 MHz through 10 MHz (where
the graph stops). This is a "low frequency" core, with impedance peaking
about 3.5 MHz.
