Rated for 160 mA continuous with a 3.9 Ohm max DCR, it is a general-purpose power or signal-line choke for surface-mount boards that do not need magnetic shielding. The self-resonant frequency is 14 MHz, tested at 1 MHz — this inductor is useful in DC-DC converter output filters and low-frequency EMI suppression where the operating frequency stays well below SRF. ## Last Buy — plan the BOM now Murata lists the LQH31CN220K03L as Last Buy. This means the manufacturer has announced end-of-life and will accept final orders within a defined window — after that, supply shifts to independent distribution. If this inductor is on your active BOM, secure the last-time-buy quantity or qualify a replacement before the order window closes. ## 1206 footprint and temperature envelope Surface-mount reflow soldering is standard; the ferrite core and unshielded construction mean the inductor radiates a small magnetic field — keep sensitive analog traces or other inductors at least one package width away. It does not carry an AEC-Q200 automotive grade — not intended for under-hood or high-vibration deployments.","metaTitle":"Murata LQH31CN220K03L 22 µH Inductor, 160 mA, 1206, Last Buy","metaDescription":"Murata LQH31CN220K03L 22 µH unshielded wirewound inductor, 160 mA, 3.9 Ohm DCR, 1206 package.
