A self-resonant frequency of 25 MHz means the inductor behaves as an inductor up to that point; above 25 MHz the parasitic capacitance dominates, so this part suits DC-DC converters and filtering below 10 MHz where the Q factor of 35 at 1 MHz gives reasonable selectivity. ## 1210 footprint for automated assembly The unshielded drum core construction means magnetic flux radiates outside the body — keep sensitive traces or low-level analog circuits at least a few millimeters away to avoid coupling.","metaTitle":"Murata LQH32NH180J23L Drum Core Inductor, 18 µH, 235 mA","metaDescription":"Murata LQH32NH180J23L drum core wirewound inductor, 18 µH ±5%, 235 mA rated current, 768 mOhm DCR, AEC-Q200 qualified.
