The 370 mA continuous current rating and 456 mOhm max DCR define the DC bias limit and the self-heating at full load — at 370 mA the I²R loss is roughly 62 mW, which stays within the package's thermal budget without forced airflow. The 650 mA saturation current (Isat) is the hard ceiling where the ferrite core saturates and inductance collapses — design the peak inductor current below this value to maintain the target ripple and avoid a sudden current spike that could stress the downstream switching FET. With a 25 MHz self-resonant frequency, this inductor is usable in DC-DC converters switching up to a few MHz — the SRF is well above the typical 500 kHz to 2 MHz switching range for point-of-load regulators, so the parasitic capacitance across the winding does not degrade the impedance at the operating frequency. ## Shielded construction and temperature range for industrial and automotive power rails The shielded ferrite core contains the magnetic flux within the component body, reducing radiated EMI to adjacent traces and nearby ICs — this matters when the inductor sits close to a sensitive analog front-end or a wireless transceiver on the same PCB. The ferrite core material maintains its permeability across this range with minimal inductance drift. Surface-mount in the 1212 (3030 Metric) package — 3.00 mm × 3.00 mm footprint with a 1.20 mm seated height. The small profile suits space-constrained designs like sensor modules, handheld instruments, and compact power modules where board height is limited. ## Active production — sourcing and lifecycle status The part is RoHS-compliant and supplied in tape-and-reel packaging suitable for automated pick-and-place assembly.","metaTitle":"Murata LQH3NPN150MJRL Shielded Power Inductor, 15 µH, 370 mA","metaDescription":"Murata LQH3NPN150MJRL Drum Core Wirewound inductor, 15 µH ±20%, 370 mA rated, 456 mOhm DCR, shielded, 1212 package, -40 to 105°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Inductors & Chokes"],"specifications":{"Mfr":"Murata Electronics","Type":"Drum Core, Wirewound","Series":"LQH3","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"-","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"15 µH","Mounting Type":"Surface Mount","Package / Case":"1212 (3030 Metric)","Product Status":"Active","Material - Core":"Ferrite","lifecycle_stage":"unknown","Size / Dimension":"0.118\\\" L x 0.118\\\" W (3.00mm x 3.00mm)","Base Product Number":"LQH3NPN","DC Resistance (DCR)":"456mOhm Max","Current Rating (Amps)":"370 mA","Height - Seated (Max)":"0.047\\\" (1.20mm)","Operating Temperature":"-40°C ~ 105°C","Supplier Device Package":"1212 (3030 Metric)","Frequency - Self Resonant":"25MHz","Current - Saturation (Isat)":"650mA","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/208315cfdd2345a13b2ab69c20848213.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the saturation current for LQH3NPN150MJRL?","answer":"The saturation current (Isat) is 650 mA.
