  1. Inductance is for the primary, measured on an Agilent/HP 4284 at 100 kHz, 0.1 Vrms, 0 Adc
  2. Minimum inductance is for the primary, measured on an Agilent/HP 4284 at 100 kHz, 0.1 Vrms, 0.4 Adc.
  3. DC current that causes an inductance drop of 30% (typ) from its value without current.
  4. Leakage inductance is for the primary with secondary winding shorted together.
  5. Isolation (hipot) measured between windings for one minute.
