메모
  1. Output is with the secondary windings connected in parallel. Output of the bias winding with a 15 V, 0.2 A
  2. When ordering, please specify packaging code: e.g. C1048-ALD
  3. Inductance is for the primary, measured at 250 kHz, 0.3 Vrms, 0 Adc.
  4. DCR is for both windings of the secondary connected in parallel.
  5. Leakage inductance is for the primary winding with the secondary windings shorted.
  6. Turns ratio is with the secondary windings connected in parallel
  7. 1500 Vrms, one minute primary to secondary isolation.
