INTRODUCTION
Because soft ferrite, such as MOFe2O3 (M:bivalent metal), in the high-frequency range has high
magnetic permeability, a large degree of saturation magnetic flux and large characteristic
resistance compared to metallic magnetic materials, it is extremely populer as a high-
frequency compound.
As switching power supplies rapidly become more compact and thinner, requirements for ferrite
as a high-frequency transformer material are becoming increasingly stringent.
To meet these demands, NEC TOKIN has enhanced its lineup of ferrite cores by adding the
BH1 and BH2 types (-300 kHz) which feature improved core loss over the B25 type (-300
kHz), and B40 (500 kHz -1 MHz) with improved core loss in high frequencies.
Further, the requirements of larger power supply capacities, increasing thinness and high
density mounting are met by the E,FPQ, FEP, FEER and FQK Series, as well as the
surface-mounting FEY Series.
●E type cores
This series features 46 shapes and sizes from FEI 12.5 to
FEE60W, standard-equipped with accessories for accommo-
dating different transformer specifications.
●FPQ type cores
This series features eight shapes and sizes suitable for high
density mounting.
●FEER type cores
This series features 19 shapes and sizes with greater winding
cross-sectional area than the E and FPQ types.
●FEY type cores
This series features htree shapes and sizes suitable for ultra
high-density mounting.
