非晶、納米晶技術(shù)是現(xiàn)代先進(jìn)的科技，直接從融熔的鋼水經(jīng)過(guò)快速冷卻成形為非晶帶材，這是冶金史上的革命。作為新型的軟磁材料，由于其獨(dú)特的優(yōu)點(diǎn)，已廣泛于高性能磁芯，電感元件，變壓器。興磁科技 King Magnetics 目前已開(kāi)發(fā)出用于共模電感的系列非晶、納米晶磁芯。
納米晶磁芯具有高的導(dǎo)磁率，頻率特性寬，非常適用于EMC濾波器，共模電感，以抑制共模噪聲。相對(duì)于傳統(tǒng)軟磁材料，比如鐵氧體磁芯，納米晶磁芯優(yōu)勢(shì)明顯，高電感量，濾波效果好，體積小，銅線匝數(shù)少。
納米晶磁芯的居里溫度高達(dá)560℃，遠(yuǎn)高于傳統(tǒng)鐵氧體磁芯只有200℃，高居里溫度使得納米晶磁芯具有高的熱穩(wěn)定性，可以連續(xù)工作于120℃。
納米晶磁芯已成為目前共模電感磁芯的優(yōu)選材質(zhì)。

We design amorphous and nanocrystalline components, chokes, inductors, transformers for customers.
Common mode choke with nanocrystalline core has the best performance compared with traditional ferrite core. And small size, low power consuption, low copper wire.
Output filter inductor made of amorphous C core can withstand large DC current, low core loss, low temperature rise, high inductance and high temperature stability.
High frequency transformer for frequency from 400Hz up to 100KHz can use amorphous and nanocrystalline core, with merits of low core loss, high saturation flux density, high efficiency.
According to clients’ drawings, requirments, we select the best solusion, the optimized core and make the excellent components.
共模電感的工作原理：
共模電感是一個(gè)高導(dǎo)磁率的磁芯上有兩個(gè)繞組，這兩個(gè)繞組的電流按同一方向流入，同一方向流出，負(fù)載電流產(chǎn)生的磁場(chǎng)在磁芯中相互抵消。當(dāng)共模噪聲流進(jìn)時(shí)，由于方向不同向，于是在磁芯中產(chǎn)生磁場(chǎng)，而由于磁芯的高導(dǎo)磁率而把噪聲抑制。
興磁科技King Magnetics的納米晶磁芯適用于共模噪聲濾波器，電感量較高，頻率寬。納米晶磁芯適用于替代傳統(tǒng)鐵氧體。
