I am struggling to understand what seems like a fundamental behavior of an inductor. I am looking at a chip mount LQM18PN2R2MFR inductor. One of the diagrams on the manufacturer's website shows a graph that describes the relationship between inductance and current. I assume this refers to DC current through the inductor.
Since there is a ferrite core in the inductor, the DC current aligns some of the magnetic domains in the core material. Is this the reason the inductance drops? If so, if I had a signal with a DC current component of 400mA, then the AC component would see an inductance of 0.8uH?
