4
) The data shown below can be sorted by Part Number, Inductance, Rated Current, DRC, or any of the columns. To sort, please click on the column headings ( first row ). To sort "Part Number" in ascending order, click "Part Number" once. Click "Part Number" once again to sort it in descending order. Click on "Inductance" to sort Inductance column in ascending or descending order, etc..

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 60 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 NO AIR FLOW.

7) The saturation current is at least 5 times the max current listed in 5 above, so instantaneous high current spikes can be tolerated by these inductors. .
