| Abstract: | As one of the three key surface-mounting passive components, multi-layer chip inductors (MLCI) are developing rapidly towards miniaturization, composition, and multi-function. In this paper, the study on a novel Co2Z-type hexaferrite material of MLCIs for very high frequency (300 MHz~1 GHz) application is reviewed, including the present technology and prospective market. Sol-gel auto-combustion process and conventional oxide reaction method were used for the preparation of the polycrystalline hexaferrite. It is found that Co2Z-type hexaferrite sintered at low temperature exhibit excellent electromagnetic properties at the very high frequency; therefore meet the requirement of the high performance MLCIs. |
