메모
  1. When ordering, please specify packaging code: e.g.UA7902-ALD
  2. Inductance is for the primary, measured on an Agilent/HP 4284 at 250 kHz, 0.1 Vrms, 0 Adc.
  3. DC current that causes an inductance drop of 30% (typ) from its value without current.
  4. DCR for secondary is for the windings connected in parallel.
  5. Leakage inductance measured between pins 1 and 3 at 250 kHz, 0.1Vrms, 0 Adc with all secondary pins shorted.
  6. Isolation (hipot) measured between windings for one minute.
