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.
