2 Core material CHOKE COILS Core material CORE Tamura's choke coils being manufactured through the study on unique features of carefully selected magnetic metal materials, under the highest levels of magnetic characteristics and electric designing technology. Magnetic metal materials provide a high saturation magnetic flux density and good stability for the humidity, which are suitable to make the cores in light weight and miniature size. Amorphous core It is core, which used the iron-base-amorphous alloy. This core is most fit for use in high frequency circuit due to the fact that it has higher saturation magnetic flux density, better at high frequency characteristics and small core loss. Moreover, by controlling heat treatment conditions, since an iron-base-amorphous material can change the magnetic characteristic, manufacture of gap-less core is possible for it. Permalloy dust core After insulation the permalloy powder of a nickel-iron alloy, it is core, which gave powder molding and heat treatment. Due to dust core, a gap penetrates equally into magnetic path length and magnetic leakage flux is smaller. Also saturation of DC Bias can be greater due to large saturation magnetic flux density. Iron alloy dust core After insulation the powder of iron alloy it is core, which gave powder molding and heat treatment. Due to dust core, a gap penetrates equally into magnetic path length and magnetic leakage flux is smaller. It is possible to offer it the core loss smaller than the permalloy dust core, and at a low price to the extent that it doesn t contain the nickel in addition. Ferrite Core This is an iron core created by the pressure-forming and thermal binding of ferric oxide powder. Compared to iron cores using other metallic magnetic materials, it possesses a high inherent resistance, which in turn means an extremely low loss rate, even at highfrequencies, and outstanding frequency response characteristics. We utilize these characteristics in the manufacture of commonmode coil products.
