Abstract

A chip inductor based on the CoTi-substituted hexa ferrite BaFe₁₂O₁₉ was designed by LTCC technology to realize the 0805 size of standard packaging and high frequency applications. Testing results show that the value of inductor is 2.45 muH and cut-off frequency is 508 MHz. And the measured results agree with the simulated data basically, which indicates that the samples can satisfy the need of high frequency inductors. The influences of each factor on the performances of inductor were also analyzed. It is an effective method to resolve the consistency problems between simulation and manufacture.
