With a 310 mA continuous current rating and a 2.14 Ω maximum DCR, it suits low-to-moderate current DC-DC converter output filters and power-supply smoothing where the 47 µH value sets the ripple current and the DCR governs the I²R loss. ## Shielded ferrite core and saturation margin The ferrite core is fully shielded, which contains the magnetic field and reduces radiated EMI into adjacent components — a practical advantage when routing the inductor near sensitive analog or RF traces on a dense PCB. The saturation current (Isat) is specified at 330 mA, only 6% above the rated current, meaning the inductance begins to roll off sharply above the 310 mA continuous limit; the design should keep the peak current below 330 mA to avoid a sudden loss of inductance and the resulting current spike. Self-resonant frequency is 11 MHz, which sets the upper bound for the inductor's impedance peak. For a buck converter switching at 500 kHz to 2 MHz, the 47 µH value stays well below self-resonance, so the inductor behaves as a pure inductive element across the switching band. ## Temperature range and board-fit dimensions The part ships on tape and reel, compatible with automated handling.","metaTitle":"Murata LQH32PN470MN0L Shielded Power Inductor, 47 µH, 310 mA","metaDescription":"Murata LQH32PN470MN0L shielded wirewound inductor, 47 µH ±20%, 310 mA rated, 2.14 Ω DCR, -40°C to 85°C.
