1 µH shielded power inductor for automotive and industrial DC-DC
The Murata LQH2HPZ1R0MGRL is a 1 µH shielded wirewound inductor in the LQH2 series, built for DC-DC converter output filtering and power rail smoothing where board space is tight. Rated for 2.1 A continuous with a saturation current of 2.13 A, the inductor's ferrite core holds the inductance flat until the current approaches the saturation ceiling — useful for a power rail that sees transient spikes above the steady-state draw. The 81.6 mOhm maximum DCR sets the I²R conduction loss; at 2.1 A that is about 360 mW of self-heating, which stays within the 105°C operating limit in most ambient conditions.
AEC-Q200 qualification and deployment context
AEC-Q200 qualified, this inductor is certified for automotive-grade stress testing — temperature cycling, mechanical shock, and vibration per the passive-component qualification standard. Shielded construction contains the magnetic flux, reducing radiated EMI into nearby traces — a consideration for noise-sensitive analog or RF stages on the same board.
The self-resonant frequency of 100 MHz is well above typical switching frequencies for automotive and industrial DC-DC converters (2-4 MHz), so the inductor behaves as a pure inductive element in-band.
