Notes
  1. Inductance is for the primary, measured at 150 kHz, 0.1 Vrms, 0 Adc.
  2. DCR for the primary is with the windings connected in parallel. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  3. Leakage inductance is measured on the primary winding with the secondary pinss shorted.
  4. 3000 Vrms, one minute primary to secondary isolation.
