The 15 MHz self-resonant frequency means the inductor's impedance remains inductive up to that point; above 15 MHz the parasitic capacitance dominates and the part behaves as a capacitor. For a buck converter switching at 500 kHz to 2 MHz, the 47 µH value and 15 MHz SRF leave plenty of headroom before the impedance roll-off. ## 1210 footprint and board-fit constraints The unshielded construction means the external magnetic field couples into adjacent traces or components — keep a clearance of at least one part width from sensitive analog or RF traces, or plan for a shield can over the area. No moisture sensitivity level is stated, but ferrite-core wirewounds of this size typically handle MSL 1 (no bake required before reflow).","metaTitle":"Murata LQH32CN470K53L 47 µH Unshielded Inductor, 170 mA","metaDescription":"Murata LQH32CN470K53L drum core wirewound inductor, 47 µH ±10%, 170 mA, 1.69 Ω DCR, 1210 footprint.
