  1. Inductance is for the primary, measured at 100 kHz, 0.1 Vrms.
  2. DCR for the primary is measured 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 for the primary winding, measured at 100 kHz, 0.1 Vrms with the secondary winding shorted.
  4. 2000 Vrms, one minute isolation from primary and auxiliary to secondary windings.
