  1. Inductance measured at 100 kHz, 0.1 V, 0 Adc using an Agilent/HP 4263B impedance analyzer or equivalent.
  2. DCR measured on Cambridge Technology micro-ohmmeter at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  3. Leakage inductance is for the primary and measured with pins 6 and 12 shorted.
  4. Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
  5. 1000 Vrms isolation winding to winding and from each winding to the core.
