Notes
  1. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/ HP 4263B impedance analyzer or equivalent.
  2. 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 with the secondary shorted.
  4. Isolation: 3000 Vrms, one minute Pri and P1 to S1 and Sense; 1500 Vrms all windings to core
