摘要
通过掺杂提高材料磁导率在磁场中的稳定性,对比得到掺杂Nb^(5+)时效果较好;分析材料参数与电感性能之间变化关系,得到材料性能随电流变化影响电感性能的关键因素之一,是电流变化引起外加磁场变化使得材料磁导率随之变化;基于以上所得,采用掺杂Nb^(5+)的铁氧体作为基板,再从结构设计方面降低磁场对材料性能的影响,最终制备得到0805型电感,额定电流为1.4 A。
The stability of magnetic permeability of material in magnetic field is improved by doping,and the effect of doping Nb^(5+) is better.The relationship of change between material parameters and inductance performance is analyzed,one of the key factors affecting inductance performance with current variation of material properties caused by the change of current is that the change of applied magnetic field caused by the change of current changes the permeability of materials.Based on the above results,Nb^(5+) doped ferrite material is used as the base plate,and reduce the influence of magnetic field on material performance from the aspect of structure design.Finally,inductance of type 0805 is prepared with rated current of 1.4 A.
