  1. Inductance measured at 100 kHz, 0.1 V, 0 Adc using an Agilent/HP 4263B impedance analyzer or equivalent.
  2. Isat: DC current at 25°C that causes the specified inductance drop from its value without current.
  3. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. SRF tested on an Agilent/HP 4192A.
  5. Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
  6. 500 Vrms isolation winding to winding and from each winding to the core.
