The 2.7 µH inductance carries a ±20% tolerance, tested at 1 MHz — the wide band means the actual value on the reel can range from 2.16 µH to 3.24 µH, which matters when the filter corner frequency is tight. ## 50 MHz SRF and unshielded construction Self-resonant frequency is 50 MHz — above this point the inductor's impedance becomes capacitive, so the part is suited for DC-DC converter output filters and power rail smoothing up to the low tens of MHz, not for RF tank circuits. The unshielded drum core with ferrite material means the magnetic field extends beyond the package — adjacent traces on the PCB should be kept clear to avoid coupling into nearby signal paths, especially in mixed-signal layouts.","metaTitle":"Murata LQH43CN2R7M33L 2.7 µH Inductor, 1.8 A","metaDescription":"Active Murata LQH43CN2R7M33L drum core wirewound inductor, 2.7 µH ±20%, 1.8 A, 69 mOhm DCR, 1812 SMD.
