It carries a continuous current rating of 540 mA and a saturation current floor of 480 mA, meaning the inductance holds stable up to that point before the core begins to saturate — a critical parameter for sizing the inductor in a buck converter's output filter where the peak inductor current exceeds the DC load current. ## Parametric fit for a power-stage inductor Maximum DC resistance of 468 mOhm sets the I²R conduction loss — at the full 540 mA rating the copper loss is roughly 136 mW, which the 105°C rated operating temperature can handle without derating in still air. The self-resonant frequency of 15 MHz sits well above the typical 1–2 MHz switching frequency of modern point-of-load converters, so the parasitic capacitance does not degrade the impedance in the passband. The shielded construction contains the magnetic field, reducing radiated EMI into adjacent traces or sensitive analog circuits on the same board.","metaTitle":"Murata LQH3NPN150MGRL Shielded Power Inductor, 15 µH, 540 mA","metaDescription":"Murata LQH3NPN150MGRL drum core wirewound inductor, 15 µH ±20%, 540 mA rated, 480 mA saturation, shielded ferrite core in 1212 package.","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)","Ratings":"-","Features":"-","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)":"468mOhm Max","Current Rating (Amps)":"540 mA","Height - Seated (Max)":"0.039\\\" (1.00mm)","Operating Temperature":"-40°C ~ 105°C","Supplier Device Package":"1212 (3030 Metric)","Frequency - Self Resonant":"15MHz","Current - Saturation (Isat)":"480mA","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1561","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ca3e274b3c8e9e5a1e2a0e200f8f6ddd.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the saturation current and why does it matter for this inductor?","answer":"The saturation current (Isat) is 480 mA. When the peak inductor current exceeds this value, the ferrite core begins to saturate and the inductance drops sharply, which can cause the output ripple current to increase and the converter to lose regulation. The 540 mA continuous current rating is the thermal limit; the saturation limit is the lower of the two at 480 mA, so the design should keep peak current below that figure."},{"question":"What package does the LQH3NPN150MGRL use and what is its footprint?","answer":"The supplier device package is also listed as 1212 (3030 Metric), meaning the standard land pattern for a 3 mm × 3 mm inductor applies."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/LQH3NPN150MGRL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/LQH3NPN150MGRL when reusing this data.
