It delivers 15 µH ±5% at 1 MHz test frequency, with a current rating of 360 mA. DC resistance is 730 mOhm max — at rated current the I²R loss is about 95 mW, which is within the dissipation of the 1812 body in still air. The self-resonant frequency sits at 19 MHz, so the inductive impedance holds up well into the low-MHz switching range before parasitic capacitance takes over. ## Q factor and frequency response Q is specified at 35 minimum at 1 MHz — a moderate figure typical of ferrite-core wirewounds in this footprint. The 19 MHz SRF means the inductor behaves as a pure inductance up to about 5-8 MHz; above that the effective inductance rolls off and the Q drops. For a buck converter switching at 500 kHz to 2 MHz, this part is comfortably below the SRF knee. ## Temperature grade and shelf life The ferrite core material does not saturate sharply with temperature in this range, but the DCR will drift up about 0.4% per °C. Store the reels in a dry environment below 40°C; the 1812 body is not moisture-sensitive per J-STD-020, but the tape-and-reel packaging should be kept sealed until use to avoid oxidation on the terminations. This is a standard catalogue part in the LQH43 series, so availability through authorized distribution is stable.","metaTitle":"Murata LQH43MN150J03L 15 µH Unshielded Inductor, 360 mA","metaDescription":"Murata LQH43MN150J03L drum core wirewound inductor, 15 µH ±5%, 360 mA, 730 mOhm DCR, 1812 package.
