Composition and process conditions for low temperature sintered NiCuZn ferrites were investigated, so as to fabricate multilayered chip inductor. The Fe₂O₃ deficiency for low temperature sintering was decreased with NiO contents of NiCuZn ferrites. The permeability of NiCuZn ferrites can be controlled in the range of 12~562 with the variation of NiO and Co₃O₄ contents. The Qmax frequency of NiCuZn ferrites was decreased from 50 ㎒ to 3 ㎒ linearly with permeability increase from 60 to 560. The relation between the Qmax frequency(Y) and permeability (X) of NiCuZn ferrites was expressed with the following empirical equation, logY=4.2-1.4 logX.
