It delivers 1 µH ±20% inductance with a rated current of 1.23 A and a saturation current of 2.25 A — the gap between rated and Isat means the core holds its inductance well into overload before rolling off. The 48 mΩ maximum DC resistance keeps I²R losses under 73 mW at full rated current — within the thermal budget of a typical 1212 footprint on a two-layer board with minimal copper pour. Shielding is integral to the ferrite core construction; the closed magnetic path reduces radiated EMI into adjacent traces and components, which matters when the inductor sits near a sensitive ADC or RF front-end on the same rail. ## Footprint, profile, and temperature envelope The surface-mount termination suits standard reflow profiles for lead-free solder. Rated for operation from -40°C to 105°C, the inductor covers industrial and automotive cabin-temperature environments. The self-resonant frequency of 100 MHz sets the usable band well above typical DC-DC switching frequencies (100 kHz to 2 MHz), so parasitic self-resonance does not intrude on the passband. ## Sourcing and compliance posture The base product number LQH3NPN covers the family; the suffix 1R0MJRL encodes the 1 µH inductance, ±20% tolerance, and packaging in Tape & Reel (TR) or Cut Tape (CT). RoHS compliance is standard for Murata's LQH3 series, though the specific directive declarations should be verified against the manufacturer's certificate at order.","metaTitle":"Murata LQH3NPN1R0MJRL Shielded Power Inductor, 1 µH, 1.23 A","metaDescription":"Murata LQH3NPN1R0MJRL drum core wirewound inductor, 1 µH ±20%, 1.23 A rated, 2.25 A saturation, 48 mΩ DCR, shielded ferrite, 1212 (3030 Metric), active","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 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)":"48mOhm Max","Current Rating (Amps)":"1.23 A","Height - Seated (Max)":"0.047\\\" (1.20mm)","Operating Temperature":"-40°C ~ 105°C","Supplier Device Package":"1212 (3030 Metric)","Frequency - Self Resonant":"100MHz","Current - Saturation (Isat)":"2.25A","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":"Where can I buy LQH3NPN1R0MJRL and how do I get a price?","answer":"The LQH3NPN1R0MJRL is available to order through independent distribution."},{"question":"What is the rated current and saturation current for this inductor?","answer":"The LQH3NPN1R0MJRL is rated for 1.23 A continuous current with a saturation current (Isat) of 2.25 A.
