For a BOM line that relies on this inductor, the immediate decision is to secure lifetime-buy quantities now or qualify a replacement before the window shuts. We source this part through independent surplus and authorized distribution channels; availability and pricing are confirmed at RFQ against your target quantity. ## Parametric profile for DC-DC and power-line filtering 4.7 µH ±20% inductance at 1 MHz test frequency, rated 910 mA continuous with a saturation current floor of 850 mA — the inductor stays in its linear region up to the saturation limit, so a 12 V to 3.3 V buck converter drawing 800 mA has margin before the inductance rolls off. Max DC resistance is 168 mOhm, which translates to roughly 140 mW I²R loss at full rated current — a manageable thermal contribution in a 1212 footprint, but worth checking against the board's copper pour for heat spreading. Self-resonant frequency is 27 MHz, well above the switching frequency of most automotive-grade DC-DC converters (typically 400 kHz to 2.2 MHz), so the inductor behaves as a pure inductive element in-band without capacitive coupling. ## Automotive-grade qualification and temperature envelope AEC-Q200 qualified — the passive-component stress test for automotive electronics. This covers temperature cycling, moisture resistance, mechanical shock, and vibration per the AEC-Q200 rev D standard, making the part suitable for under-hood and cabin-environment ECUs that see -40°C to 105°C ambient. Shielded ferrite core construction contains the magnetic field within the 3.00 mm × 3.00 mm footprint, reducing crosstalk to adjacent traces and allowing tighter component spacing on the PCB.","metaTitle":"Murata LQH3NPZ4R7MGRL 4.7 µH Shielded Inductor, 910 mA","metaDescription":"Murata LQH3NPZ4R7MGRL drum core wirewound inductor, 4.7 µH, 910 mA, AEC-Q200, shielded.
