Planar EE cores, and Planar EI cores, with their low profile are suitable for board level installation allowing
assembly without the need for plastic coilformers and can also allow windings integrated into multi-level PCBs.
Planar ER cores with their low mass and low profile are suitable for Surface Mount installations in low power
filter and transformer applications.
-Planar EE, ER and EI cores can be supplied with the center post gapped to a mechanical dimension or an AL value.
-AL value is measured at 1 kHz, B < 10 gauss.
-Weight indicated is per pair or set.

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
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.
A ½ turn is defined as a single pass through a hole.
