  1. Inductance measured at 1 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4192A impedance analyzer or equivalent.
  2. DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
  3. SRF measured on an Agilent/HP 8753D network analyzer.
  4. Isat: DC current at which inductance drops 10% (typ) from its value without current. 
  5. Irms: Crrent that causes a 40°C rise from 25°C.
