The characteristic of iron-base nanometer crystal alloy:
1. high saturated magnetic induction: the Bs of iron-base nanometer crystal alloy reaches 1.2T, is more than ferritic twice. As common mode inductance iron core, it is saturated that important principle is that iron core can not be magnetized into, otherwise inductance value dramatic drop-off. And in actual applications, have the interference strength relatively big (such as high-power frequency conversion motor) of many occasions, if with common ferrite as common mode inductance, there is saturated probability in iron core, it is impossible to ensures the noise suppression effect under the interference of big intensity. Due to the high saturated magnetic induction of nanometer crystal alloy, its anti-saturation characteristic is substantially better than ferrite undoubtedly so that nanometer crystal alloy is highly suitable for the strongly disturbing occasion of heavy current; 2. the temperature stability of brilliance: the Curie temperature of iron-base nanometer crystal alloy is up to more than 570 DEG C. When there being bigger temperature fluctuation, the performance change rate of nanometer crystal alloy, significantly lower than ferrite, has excellent stability, and the change of performance is close to linearly. Usually, nanometer crystal alloy is at-50 DEG C---and in the temperature range of-130 DEG C, the rate of change of main magnetic property is within 10%. By contrast, ferritic Curie temperature is typically in less than 250 DEG C, and magnetic property rate of change is sometimes up to more than 100%, and in non-linear, not easily compensates. This temperature stability of nanometer crystal alloy, in conjunction with its distinctive low loss characteristic, provides loose temperature conditions for device designer. 3. frequency characteristic flexibly: by different manufacturing process, nanocrystalline iron core can obtain different frequency characteristics, coordinate suitable coil turn can obtain different impedance operators, meet the filtering requirements of different-waveband, and its resistance value is much higher than ferrite. It it is noted that any wave filter all can not look to just can realizing with a kind of core material the noise suppressed of whole frequency range, but different core material, size and number of turn etc. should be selected according to the filtering frequency range of filter specifications. Compared with ferrite, nanometer crystal alloy can obtain required frequency characteristic by adjusting process more neatly.
Do not elaborate in this specification part, for techniques known.
