EP core

EP core
Description:

EP Cores are round center-post cubical shapes, which enclose the coil completely. This particular shape minimizes the effect of air gaps formed at mating surfaces in the magnetic path and provides a larger volume ratio to total space used. Shielding is excellent.
Special advantages of ferrite EP core assemblies: wide core selection like; high packaging density on PCBs; choice of linear or flat temperature characteristics; consistency and uniformity.
