摘　　要：高性能功率电感要求磁心所用的NiZn铁氧体材料具有优良的耐热冲击能力和较好的直流叠加性能。通过传统氧化物法制备了NiZn铁氧体材料TN35H。测试证明,相对于一般NiZn材料,一方面TN35H材料的耐热冲击能力有明显提升;另一方面TN35H的饱和磁通密度大幅度提升,从而其直流叠加特性也显著提升。High performance power inductor requires NiZn ferrite material with excellent thermal shock resistance and good DC bias property. NiZn ferrite material TN35H was fabricated by conventional oxide ceramic method. Compared with conventional NiZn material, on one hand, the thermal shock resistance of TN35H was improved; on the other hand, the saturation magnetic flux density of TN35H material increases remarkably, and resultantly its DC bias characteristics was improved as well.
