It can be typically used in high frequency common mode inductors and ADSL wide-band transformers.

Electromagnetic interference(EMI) in high-speed digital circuit is mainly generated by Common-mode(CM) noise,and the CM inductance is responsible for CM noise magnitude.

The preparing methods,key technology,current status at home and abroad and the development directions of multilayer chip inductor,as well as the present research state of the materials fort MLCI At the same time the market and present and reviewed prospect of MLCI is forecaste

I have designed the multilayer chip inductor take this material as the foundation and discussed a little influences of the metal wire arrangement structure and via in the parameters of inductor.

The status and the development tendency of the low-temperature-sintering hexagonal ferrites used in the chip inductor were introduced .

In this paper, the influence of Cu2+ content on the sintering and electromagnetic properties of the low-temperture sintered MgCuZn ferrite were mainly introduced by summarizing and analyzing related literatures, and the probability of using MgCuZn ferrite as the core material for multilayer chip inductors was disscussed.
