) The data shown below can be sorted by clicking each column header.Click once again to sort in reverse order.
5 ) "Inductance at 1 Khz" ( 2nd column from left in table below ) is the inductance measured at zero or very low DC bias current.
6 ) "Current Rating" ( 3rd column from left in table below ) is based on a 40 deg C temperature rise at an ambient temperature of 90 deg C. This is the DC bias current through the inductor that will cause the inductor will reach a max. temp. rise of 40 deg C. above ambient with some AIR FLOW.
7 ) The saturation current is at least 5 times the max current listed in 5) or 6) above, so instantaneous high current spikes can be tolerated by these inductors.
8) "Dimensions:"

  • A = Outer Dimension
  • B = Height
  • C = Vertical Mounting Hole Distance
  • D = Lead length
  • E = Lead Width
  • F = Horizontal Mounting Hole Distance
