Preparation of nanocrystalline alloy rod inductor and analysis of broadband constant inductance characteristics
In order to research and fabricate miniature rod inductors with high performance nanocrystalline alloy rod magnetic core is prepared by curing,wire cutting,sectional annealing and other techniques of Fe-based amorphous ribbon,and the nanocrystalline alloy rod inductor is prepared on this basis.The performance of the rod inductance is measured and analyzed by the IM3570 inductance measuring instrument,and the inductance calculation model with magnetic core rod inductor is modified.The results show that the inductance and its quality factor of the prepared nanocrystalline alloy rod micro-inductor are range of 7.72～9.93μH and 3.33～5.14 respectively in the frequency range of 0.112～3 MHz,by which the inner wall coating in circuit board hole can be distinguished effectively at 300 kHz .
