It delivers 2.7 µH inductance with ±5% tolerance, rated for 950 mA continuous current. ## DC resistance and self-resonant ceiling Maximum DC resistance is 63.6 mOhm. At 950 mA the I²R loss is about 57 mW — negligible for the 1812 body but worth checking against the board's local thermal budget if the inductor sits near a hot regulator. Self-resonant frequency is 53 MHz, well above the 1 MHz test frequency. The Q factor is 20 at 1 MHz — typical for a ferrite-core wirewound in this inductance range. For a DC-DC converter switching at 2-4 MHz, the inductor's impedance stays inductive up to about 10× the switching fundamental.","metaTitle":"Murata LQH43NH2R7J03L Drum Core Inductor, 2.7 µH, 950 mA","metaDescription":"Murata LQH43NH2R7J03L wirewound inductor, 2.7 µH ±5%, 950 mA, 63.6 mOhm DCR, AEC-Q200, 1812 package.
