Shielded 1.5 µH power inductor for DC-DC rail filtering
The Murata LQH3NPN1R5MGRL is a shielded drum core wirewound inductor in the LQH3 series, delivering 1.5 µH ±20% inductance with a 1.22 A continuous current rating and an 88.8 mOhm max DCR. The 1.4 A saturation current (Isat) sits above the rated current, giving headroom for transient spikes in switch-mode power supply outputs without the inductance collapsing under load.
1212 footprint and board-level integration
The ferrite core and shielded construction reduce radiated EMI, making the inductor suitable for noise-sensitive circuits adjacent to RF or analog signal chains.
Self-resonant frequency and operating envelope
With an 80 MHz self-resonant frequency, the inductor maintains its inductive impedance well above the switching frequencies of common buck and boost converters, so the effective inductance holds across the converter's operating band.
