The ferrite core and unshielded construction make it a fit for low-frequency filtering and decoupling where the 5.5 MHz self-resonant frequency sets the usable ceiling — above that the inductor behaves capacitively. ## Parametric limits that govern the design decision The 65 mA current rating is the DC bias ceiling at 25 °C — above this the inductance rolls off as the core approaches saturation. For a filter carrying 50 mA DC with a 20 mA ripple, the peak current stays within the linear region. The 11.8 Ohm DCR produces 51 mW of I²R loss at rated current — negligible in most circuits, but the voltage drop across the winding at 65 mA is 0.77 V, which matters if the inductor sits in a low-voltage rail. The Q factor of 40 at 796 kHz confirms moderate AC loss in the AM broadcast band. The unshielded body means stray magnetic fields couple into nearby traces — keep sensitive analog or RF routing at least two part-widths away. ## Active lifecycle and procurement posture If a second-source is needed, the search should match the inductance, current rating, DCR, and footprint simultaneously.","metaTitle":"Murata LQH32MN221K23L 220 µH Drum Core Inductor, 65 mA","metaDescription":"Murata LQH32MN221K23L 220 µH unshielded wirewound inductor, 11.8 Ohm DCR, 65 mA rated current, 1210 footprint.
