Maximum DC resistance of 2.8 Ohm means the I²R loss at full rated current is about 63 mW — acceptable for a 1210 footprint but a significant efficiency penalty if the inductor is used near its current ceiling in a battery-powered rail. Self-resonant frequency of 14 MHz defines the upper bound for effective inductive impedance — above this frequency the component behaves capacitively, so it is not suitable for filtering switching noise above roughly 7 MHz (half the SRF). ## Unshielded drum-core — layout implications Unshielded wirewound construction on a ferrite core means the magnetic field radiates from the component — adjacent traces carrying analog signals or RF should be spaced at least one component width away to avoid coupling noise. Q factor of 35 at 1 MHz is typical for a drum-core inductor at this inductance value — adequate for tuned circuits or resonant converters operating near the test frequency, but not a high-Q part for narrowband RF filters. ## 1210 SMD footprint — assembly and supply Supplied in Tape & Reel for volume production or Cut Tape for prototypes — reel quantities suit automated assembly lines; Cut Tape avoids minimum-order overhang for small-batch builds or rework.","metaTitle":"Murata LQH32MN220K23L 22 µH Unshielded Inductor, 150 mA","metaDescription":"Murata LQH32MN220K23L drum-core wirewound inductor, 22 µH ±10%, 150 mA, 2.8 Ohm DCR, unshielded, 1210 SMD.
