The 600 mOhm DCR at 425 mA produces about 108 mW of self-heating — negligible for most board-level power rails, but worth factoring into the thermal budget if the inductor sits near a hot regulator or in a confined enclosure. Unshielded construction means the magnetic field radiates into the surrounding board area; keep sensitive analog traces or high-impedance nodes at least a few mm away from the body. ## Frequency ceiling and Q factor Self-resonant frequency is 100 MHz, so the inductor behaves as an inductor up to roughly that point — above SRF the impedance turns capacitive. Q factor is 20 at 1 MHz, which is the test frequency for the inductance value; at higher frequencies the Q typically rises then falls toward SRF. ## Package, temperature, and board-fit Operating temperature range is -40°C to 85°C, covering most industrial and commercial environments but not extended automotive under-hood conditions. Supplied in tape and reel — the base product number is LQH32MN, so the reel marking and packaging label carry the full 12-digit order code.","metaTitle":"Murata LQH32MN1R2M23L 1.2 µH Unshielded Inductor, 425 mA","metaDescription":"Murata LQH32MN1R2M23L drum core wirewound inductor, 1.2 µH ±20%, 425 mA, 600 mOhm DCR, 100 MHz SRF, -40 to 85°C.
