It carries AEC-Q200 qualification, meaning it passes the stress tests required for automotive-grade passive components — thermal shock, moisture resistance, and mechanical vibration per the AEC-Q200 rev D standard. Rated at 430 mA DC with a saturation current floor of 260 mA, the part suits low-to-mid current power rails where the inductor must hold its inductance under bias. The 1.908 Ω maximum DCR means I²R losses at full rated current reach roughly 0.35 W — a figure that drives the self-heating and must be budgeted in the thermal design of a compact 3 mm × 3 mm footprint. ## Parametric fit for DC-DC input and output filtering The self-resonant frequency of 3 MHz sets the upper bound for the converter switching frequency — above that, the inductor behaves capacitively and filtering collapses. For a buck converter switching at 1–2 MHz, the 100 µH value provides ripple current attenuation consistent with continuous conduction mode at moderate load. The ferrite core material is stable across this range, though DCR increases with temperature per the copper winding's positive temperature coefficient. Shielded construction contains the magnetic flux within the core, reducing radiated EMI that could couple into adjacent signal traces or sensitive analog circuits on the same board layer. This is a practical advantage when the inductor sits near a high-impedance ADC input or a clock line.","metaTitle":"Murata LQH3NPH101MMEL 100 µH Shielded Inductor, 430 mA","metaDescription":"Murata LQH3NPH101MMEL drum core wirewound inductor, 100 µH ±20%, 430 mA rated, 1.908Ω DCR, AEC-Q200, shielded 1212 package.
