Parametric fit for the BOM line
The Murata LQH2HPN100MGRL is a 10 µH shielded wirewound inductor from the LQH2 series, built for surface-mount placement in a 1008 (2520 Metric) footprint. Rated at 710 mA continuous with a saturation current of 700 mA, the part delivers usable headroom for a DC-DC converter output stage where the peak inductor current stays under the saturation floor to avoid a hard roll-off in inductance. A maximum DC resistance of 672 mOhm sets the I²R conduction loss at full load to roughly 0.34 W — within the dissipation limit of the 1008 body for a typical 85 °C ambient, but worth checking against the local board temperature if the inductor sits near a hot regulator or in a confined enclosure.
Shielding and self-resonant behaviour
The shielded construction contains the magnetic field within the core, so this inductor is suited for layouts where the part sits close to sensitive analog traces or a neighbouring inductor — the shield reduces cross-coupling that would otherwise shift the effective inductance or inject noise into adjacent signal paths. A self-resonant frequency of 30 MHz means the component behaves as an inductor up to roughly that point; above it the parasitic capacitance dominates and the impedance turns capacitive. For a switching regulator running at 1–2 MHz the margin is comfortable, but a filter or resonant circuit operating near 30 MHz should treat the SRF as the usable ceiling.
Temperature range and operating environment
For applications that push beyond 85 °C ambient, a wider-temperature inductor from the same LQH2 family would be the next step.
