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 NO AIR FLOW. 
7) "Inductance @ Rated Current is the Inductance value when applying the rated DC bias current." ( 4th column from left in table below ). At this current, the temperature rise may be above the 40 deg C stated above, so forced air flow may be required.
8) 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.
9) "Dimensions:"

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