The 60 mA continuous current rating and 9.12 Ω max DCR define the DC bias limit and the resistive loss — for a low-current filter or resonant tank, the DCR sets the I²R heating and the voltage drop across the part. The unshielded ferrite-core construction means the magnetic field extends beyond the package — adjacent traces or components on the same layer need clearance to avoid coupling, especially in a dense automotive ECU layout. Rated AEC-Q200, this inductor meets the stress-test and reliability requirements for automotive-grade passive components — temperature cycling, mechanical shock, vibration, and solder-heat resistance are all qualified. ## Self-resonant frequency and Q — where the inductor stops being an inductor Self-resonant frequency is 6 MHz; above this point the parasitic capacitance dominates and the component behaves capacitively. The Q factor is 40 at 1 MHz, giving a usable inductive band from low frequency up to a few MHz — suitable for EMI filter chokes, LC tank circuits, or DC-DC converter output filters where the switching fundamental sits below 2 MHz.","metaTitle":"Murata LQH32NH181J23L Inductor, 180 µH, 60 mA, AEC-Q200","metaDescription":"Murata LQH32NH181J23L drum core wirewound inductor, 180 µH ±5%, 60 mA, 9.12 Ω DCR, AEC-Q200.
