At that current the 25 Ohm max DCR drops about 1.1 V and dissipates roughly 50 mW — the self-heating is low, but the voltage drop matters if this sits in a low-voltage rail with limited headroom. AEC-Q200 qualification means this inductor passed the automotive-grade stress tests: thermal shock, humidity bias, mechanical shock, and vibration. ## Unshielded ferrite core — layout and coupling considerations The ferrite core is unshielded, so the magnetic field extends beyond the 1210 (3225 metric) footprint. Adjacent traces carrying sensitive analog signals or high-impedance nodes should be kept at least one part-width away to avoid parasitic coupling. The self-resonant frequency is 5 MHz — above that the inductor behaves capacitively, so the usable band stops well below 5 MHz for filter applications. Q factor is 50 minimum at 796 kHz — the AC loss at that frequency is moderate, making this part better suited for general-purpose filtering than for high-Q tuned circuits where a Q of 80 or higher is typical. ## Active production — no obsolescence watch needed The base product number LQH32NZ covers a family of inductors in the 1210 package with the same footprint. If a different inductance or current rating is needed later, the pin-compatible sibling within the LQH32NZ series can be substituted without a board spin.","metaTitle":"Murata LQH32NZ471J23L 470 µH Inductor, 45 mA, AEC-Q200","metaDescription":"Murata LQH32NZ471J23L drum core wirewound inductor, 470 µH ±5%, 45 mA, 25 Ohm DCR, AEC-Q200.
