MnZn ferrites have a high permeability but also a low resistivity and are most effective at low frequencies. The ferrite 3S3 and 3S4 have a higher resistivity and are real wideband materials as well.

While NiZn ferrites just on the contrary. They have a lower permeability but much higher electrical resistivity, which even up to 1000 MHz. NiZn ferrite used to be the only suitable material for EMI suppression up to GHz frequencies. Their high resistivity (105Ωm) ensures that eddy currents can never be induced in these ferrites. As a result, they maintain an excellent magnetic performance up to very high frequencies.

The new MnZn material 3S4, however, does suppress EMI up to frequencies of 1 GHz and higher, making it an attractive alternative to NiZn materials. Up to now the low resistivity of MnZn ferrites (1 to 10Ωm ) has limited their operation to a maximum of about 30 MHz. With 3S4 precise control of material composition has resulted in an increase of its resistivity to a value of 103Ωm, intermediate between the standard MnZn and NiZn grades, but high enough for effective RFI-suppression into the GHz region.

Our 3S4 ferrite cores won high reputation from our customers because of the good quality and reasonable price. Any inquiry on custom size is welcome.
