Rated for 250 mA continuous current with a maximum DC resistance of 923 mOhm, this part suits power rail filtering or signal conditioning where the 19 MHz self-resonant frequency keeps the inductor inductive well above the switching noise band of a typical 1–2 MHz DC-DC converter. ## Parametric fit for power and signal paths Unshielded construction means the inductor's magnetic field couples into nearby traces — keep a 2–3 mm keep-out zone around the body on the PCB layout, or switch to a shielded variant if the board has sensitive analog or RF circuitry within that radius.","metaTitle":"Murata LQH32DN220K23L 22 µH Unshielded Inductor, 250 mA","metaDescription":"Murata LQH32DN220K23L drum core wirewound inductor, 22 µH ±10%, 250 mA, 923 mOhm DCR, unshielded, 1210 package.
