Abstract：The continuous acceleration of the development process of global informatization, networking and digitization has promoted the rapid progress of electronic technology. Integration, miniaturization and high power have become the new demands of the current market for electronic devices. The new integrated inductor with its small size, low loss, corrosion resistance, high reliability characteristics quickly occupies the electronic market share. FeSiCr soft magnetic composites have attracted wide attention due to the advantages of high resistivity, high saturation magnetic induction, high inductance, excellent DC superposition characteristics, good temperature stability, high rust resistance and higher cost performance, which made FeSiCr soft magnetic composites becoming an ideal material for integrated inductors. In this review, we summarized the latest research progress on FeSiCr soft magnetic composites from the alloy composition design, powder preparation technology, insulation coating modification, powder pressing and heat treatment process, hoping to provide references for further research and wide application of FeSiCr soft magnetic composites with better comprehensive properties.
