The 288 mOhm max DCR produces roughly 0.41 W of I²R loss at full rated current — that heat must be managed within the 3.00 mm × 3.00 mm 1212 footprint, so the board copper area under the part matters for thermal performance. ## Shielded construction and saturation margin for switching regulator inputs The ferrite core and shielded winding reduce radiated EMI compared to an unshielded drum core — useful when the inductor sits near a wireless receiver or a sensitive analog front-end. Saturation current is specified at 810 mA, meaning the inductance drops by 30 % at that DC bias; the 1.2 A rated current is thermally limited, so the part will saturate before it overheats if the DC bias exceeds 810 mA. Self-resonant frequency is 30 MHz, well above the typical 1–2 MHz switching frequency of a modern automotive buck converter, so parasitic self-resonance does not affect the filter response.","metaTitle":"Murata LQH3NPZ100MJRL 10 µH Shielded Inductor, 1.2 A","metaDescription":"Active production AEC-Q200 shielded wirewound inductor, 10 µH ±20%, 1.2 A, 288 mOhm DCR, 1212 footprint.
