The E core geometry offers an economical design approach for a wide range of inductive applications. The 77 and 78 materials are used in a variety power designs. The high permeability 75 material is utilized for matching, broadband transformers.

• Part number is for a single core.

• E cores can be supplied with the center post gapped to a mechanical dimension. E cores can also be gapped to an Al value. These cores will be supplied as sets. For any gapped E core requirement contact our customer service group.

• Al value is measured at 1 kHz, < 10 gauss.

• See "The Effect of Direct Current on the Inductance of a Ferrite Core", Figure 4 for information on Al vs. gap length.

• Fair-Rite equivalents to lamination sizes:
