Nanocrystalline Cores for Common Mode Chokes

Amorphous and nanocrystalline technologies are very important technology in modem magnetic materials, cores and inductive components. After long  term experiment and development,yongwnag technology has developed series of high quality nanocrystalline cores for common mode chokes.

Nanocrystalline cores have very high permeability over low frequency to high frequency. They are very suitable for common mode chokes used as EMC filters to compress conducted common mode noise. Compared to traditional ferrite cores, nanocrystalline cores have a lot of advantages as high inductance, good filter effective, small size and volume, lower turns of copper wire, lower power consumption and high efficiency.

Nanocrystalline cores have very high curie temperature about 560℃, much higher than traditional ferrite core about 200℃. High curie temperature make nanocrystalline core excellent thermal stability, and can continuous working at up to 120℃ environment. Nanocrystalline cores is the best choice for application of common mode choke.

非晶纳米晶技术是现代磁性材料的一项重要技术，咏旺科技通过这项技术的研发，已开发出了共模   电感用的优质纳米晶磁芯系列产品。

纳米晶磁芯具有极高的导磁率，频宽特性好，非常适用于低频至 10MHz 的传导干扰噪声滤波。相比传统铁氧体，纳米晶具备以下优点：高电感量，良好滤波特性，体积小，绕线圈数少，高效节能。

纳米晶磁芯居里温度高达 560℃，而铁氧体只有约 200℃。高的居里温度使得纳米晶磁芯具有极好的温度稳定性，可以连续工作于 120℃环境。纳米晶磁芯是共模电感的首选材质。
