Ferrite E, I and U Cores
E cores are
less expensive than pot cores and have the advantages of simple bobbin
winding and easy assembly. Gang winding is possible for the bobbins
used for these cores. E cores do not, however, offer
self-shielding.
Lamination size E shapes are available to fit
commercially available bobbins previously designed to fit the strip
stampings of standard lamination sizes. Metric and DIN sizes are
also available. Many E cores can be pressed into different
thicknesses,
providing a selection of cross-sectional areas. Bobbins for these
different cross-sectional areas are often available. E
cores can be mounted in different directions, and if desired, provide a
low profile. Printed circuit bobbins are available for low-profile
mounting. E cores are popular shapes due to the lower cost, ease of
assembly and winding, and the ready availability of a variety of hardware.
