Preferred parts, the suggested choice for new designs,have shorter lead times and are more readily available.
The column H(Oe) gives for each bead the calculated dc bias field in oersted for 1 turn and 1 ampere direct current. The actual dc H field in
A ½ turn is defined as a single pass through a hole.
A e : Effective Cross-Sectional Area
A L - Inductance Factor
N/AWG - Number of Turns/Wire Size for Test Coil

the application is this value of H times the actual NI (ampere-turn) product. For the effect of the dc bias on the impedance of the bead material,
see figures 18-23 in the application note How to choose Ferrite Components for EMI Suppression.
