Ferrite cores - guide on the limits of surface irregularities - part 3 : etd - cores and e - cores
鐵氧體磁心表面缺陷極限導則第3部分: etd和e形磁心These consist of a series of small ferrite cores of maximum diameter 2mm.
這些由一系列最大直徑為2毫米的小鐵氧體磁心組成。Hollow ferrites particles are the alternative to conventional solid ferrites particles, which have lower density, larger specific surface area and stability. moreover, it is expected electromagnetic wave can be reflected and absorbed again and again in the cavum of hollow particles which become its black hole. in addition, their electromagnetic parameters can be adjusted in a certain range by changing the thickness of the shell and the diameter of hollow microspheres, and the ability of absorbing microwave can be expected to improve
空心結構的鐵氧體是對傳統實心鐵氧體的改造，不僅密度小，還具有特殊的電、磁功能，有可能使電磁波在其空腔中反復振蕩吸收，成為電磁波的「黑洞」 ，從而增加材料的吸波能力，同時可通過調節核殼粒子的內外徑來調控電磁參數。Tas ferrite cores - technology approval schedule
