Note N/A
  • Inductance test @ 10 KHz, 1 Vrms
  • Isat is DC current at which the inductance drops the specified amount from its original value without bias.
  • Irms is the DC current that causes the specified temperature rise of the winding from 25ºC ambient for the inductor.
  • Add V for Vertical Mount, H for Horizontal Mount
