摘　　要：高导磁纳米晶磁芯以及共模电感的电磁干扰抑制性能优越。为探讨大规模推广使用纳米晶共模电感的可行性,文章比对了锰锌铁氧体、纳米晶两种材质磁芯样品的一系列测试结果,并将锰锌铁氧体和纳米晶共模电感搭载至实际电子产品上进行电磁传导发射测试。结果表明,同等尺寸、同等匝数的纳米晶共模电感在器件的阻抗、感值、共模插损、漏感性能,实际搭载产品的电磁传导发射测试效果,以及磁导率、磁芯损耗、热稳定性等方面均远高于锰锌铁氧体。纳米晶共模电感可通过缩小体积达到与锰锌铁氧体相近甚至更低的生产成本。综合考虑电磁性能、实用性等,新一代纳米晶共模电感可以大规模推广使用。The electromagnetic interference suppression performance of high permeability nanocrystalline magnetic cores and common mode choke is superior.To explore the feasibility of promoting the use of nanocrystalline common mode choke on a large scale,this article compared a series of test results of magnetic core samples made of manganese zinc ferrite and nanocrystalline materials,and carried out electromagnetic conduction emission tests on actual electronic products using manganese zinc ferrite and nanocrystalline common mode choke.The results show that nanocrystalline common mode choke of the same size and number of turns have significantly higher impedance,inductance,common mode insertion loss,leakage inductance performance,electromagnetic conduction emission testing performance of actual products,as well as magnetic permeability,core loss,thermal stability,etc.compared to manganese zinc ferrite.Nanocrystalline common mode choke can achieve production costs similar to or even lower than manganese zinc ferrite by reducing their volume.Taking into account electromagnetic performance,practicality,and other factors,the new generation of nanocrystalline common mode choke can be widely promoted and used.
