As IT and electronic devices become small and improve its performance,
issues of electromagnetic noise are addressed. EMC regulations for those
devices have been tighten and, consequently, need for high efficiency noise
reduction components is urged for electronic devices.

using FINEMET®, the first nanocrystalline soft magnetic material in the
world, to meet this requirements.
The FINEMET® EMC components offer superior technical solution for
electromagnetic noise suppression, size reduction and low energy loss for
your application.

What is FINEMET®?
The first nanocrystalline soft magnetic material in the world developed by Hitachi Metals, Ltd. The precursor material of FINEMET® is amorphous metal obtained by rapid quenching the molten metal, consisting of Fe, Si, B
and small amounts of Cu and Nb. By applying heat treatment to the alloy at higher temperature than its crystallization
temperature, this alloy forms Nano-Crystalline structure (grain size of approximately 10 nanometer).
Provided with both high saturation magnetic flux density and high permeability.FINEMET® has high saturation magnetic flux density (more than 1T) comparable to Fe-based amorphous metal and high
permeability (over 10,000 at 100kHz) comparable to Co-based amorphous metal. It has the advantages of both Fe based and Co
based amorphous metals.
Excellent temperature characteristics.FINEMET® has very high Curie temperature (570˚C) which results in small permeability variation (less than +/-10%) at a
temperature range from -40 to +150˚C.
Less affected by mechanical stress, and very low audible noise emission.FINEMET's permeability and core loss are hardly affected by mechanical stress due to near-zero magnetostriction (less than 10-6).
Furthermore, its low magnetostriction significantly reduces audible noise emission when the voltage and current applied to the
core at audible frequency range.

Features for cores made of "FT-3KM" The cores made of high permeability FT-3KM have the following advantages over commonly used Mn-Zn ferrite cores:
In the product line of FINEMET® common mode choke cores, there are two types of cores made of (1) high permeability material "FT-3KM" and (2) high saturation-field material "FT-3KL". Both cores have high impedance in wide frequency range.
1) Four times higher impedance due to high impedance permeability, The real part of complex permeability (μr') at 100kHz and 20℃ reaches more than twice as high as that of Mn-Zn ferrite cores. The impedance relative permeability (μrz) including imaginary part of complex permeability (μr") reaches more than four times as high as that of Mn-Zn ferrite cores. The cores shows following benefits (Table 15, Figure 50, 51):
・ The coils have four times higher impedance with same
winding turns. ・ Winding turns can be 1/2 reduced to obtain same impedance. ・ Reducing winding turns allow significant reduction of stray capacitance, which result in having large impedance in high frequency range.
2) Stable magnetic properties against temperature change.
Inductance and impedance of the common mode chokes are very stable against temperature change due to high Curie temperature. (Figure 52, 53).

Features for cores made of "FT-3KL" The cores made of FT-3KL with high saturation-field property have the following advantages:
1) High saturation-field and low residual magnetic flux density in B-H curve The cores have excellent DC superposed characteristics due to its high permeability and high saturation-field property in B-H curve (Figure 54, 55). The cores can suppress surge current with high volt-second due to high maximum induction swing (ΔBm) resulting from low residual magnetic flux density (Figure 56).
2) High impedance over wide frequency range. These cores have excellent performance in noise reduction in wide frequency range from conduction noise to radiation noise. In particular, these cores show high performance in noise reduction at 1MHz-100MHz due to higher impedance than other materials (Figure 57).

●FT-3KM S series
Table 23. Product code, part name and specifications
FT-3KM S series "square shaped" common mode choke cores are designed specifically for bus bar systems. Unlike toroidal cores, these square shaped cores allow utilizing space effectively in a switchboard. In addition, these cores are far lighter weight compare to Mn-Zn ferrite cores with the same performance.
