The 58.8 mOhm max DCR keeps I²R losses manageable at 1.1 A — about 71 mW dissipation — so the part stays cool in a dense layout without forced airflow. The self-resonant frequency of 60 MHz sits well above the 1–4 MHz switching range of most buck converters, meaning the inductive impedance dominates at the switching frequency and the SRF won't cause a parallel-resonance dip in the filter response. ## 1212 footprint and rework reality The shielded construction means it won't couple switching noise into nearby traces — a real help when the inductor sits next to a sensitive feedback node on a tight PCB. ## Sourcing and compliance posture The base product number LQH3NPN covers the family; the suffix JRL indicates the ±20% tolerance and tape-and-reel packaging. No official cross-reference or second-source is recorded for this exact inductance/tolerance/package combination. If a BOM calls for 1.5 µH ±20% in a 1212 shielded footprint, this is the Murata direct fit.","metaTitle":"Murata LQH3NPN1R5MJRL 1.5 µH Shielded Inductor, 1.1 A","metaDescription":"Murata LQH3NPN1R5MJRL, LQH3 series, 1.5 µH ±20% shielded wirewound inductor. 1.1 A rated, 1.95 A saturation, 58.8 mOhm DCR. 1212 (3030 Metric) SMD.","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":"1.5 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)":"58.8mOhm Max","Current Rating (Amps)":"1.1 A","Height - Seated (Max)":"0.047\\\" (1.20mm)","Operating Temperature":"-40°C ~ 105°C","Supplier Device Package":"1212 (3030 Metric)","Frequency - Self Resonant":"60MHz","Current - Saturation (Isat)":"1.95A","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 vs rated current on this inductor?","answer":"The continuous current rating is 1.1 A, and the saturation current (Isat) is 1.95 A.
