Notes
  1. Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc.
  2. DCR for the secondary is for each winding. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  3. Leakage inductance is for the primary and is measured at 100 kHz, 0.1 Vrms with all other windings shorted.
  4. Turns ratio for the secondary is with the windings connected in parallel.
  5. Isolation is from the primary to all other windings, tested for one minute.

Termination:
