22 µH, 160 mA — the LQH31CN220K03L fit check
The Murata LQH31CN220K03L is a 22 µH unshielded wirewound inductor in a 1206 (3216 metric) footprint. 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.
