Murata has introduced the LQM18JN series, a 1.6mm × 0.8mm × 0.55mm chip inductor ideal for NFC matching circuits in smart phones.

An NFC circuit uses a chip inductor for impedance matching, however, current with large amplitude flows in an NFC matching circuit. With a common matching inductor, the effect of magnetic saturation hinders expected performance.

Murata's inductor has a ±5% narrow deviation and can resist magnetic saturation and suppress interference with surrounding components even at high mounting density.
