It delivers 10 µH inductance at 1 MHz test frequency, rated for 480 mA continuous current with a maximum DC resistance of 240 mOhm. ## Current rating and DCR trade-off The 480 mA current rating is the saturation or temperature-rise limit — at this current the inductance drop or self-heating stays within the design margin. The 240 mOhm max DCR sets the I²R conduction loss at 55 mW at full rated current, a manageable figure for the 1812 package's thermal dissipation. Unshielded construction means the magnetic field extends beyond the component body — keep sensitive traces or other magnetics at least one package width away to avoid coupling. The ferrite core material provides stable inductance over frequency up to the 23 MHz self-resonant point. Q factor of 35 at 1 MHz indicates moderate energy storage efficiency at that frequency; above self-resonance the inductor behaves capacitively and the Q drops off rapidly. AEC-Q200 qualification means the part has passed automotive-grade stress tests including thermal shock, moisture resistance, and mechanical vibration — it is approved for use in under-hood and cabin electronics without additional qualification by the Tier-1 integrator.","metaTitle":"Murata LQH43NH100J03L Inductor, 10 µH, 480 mA, 1812","metaDescription":"Murata LQH43NH100J03L drum core wirewound inductor, 10 µH ±5%, 480 mA, 240 mOhm DCR, 1812 SMD, AEC-Q200 qualified, -40°C to +125°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":"LQH43","Package":"Tape & Reel (TR); Cut Tape (CT)","Ratings":"AEC-Q200","Features":"-","Q @ Freq":"35 @ 1MHz","Shielding":"Unshielded","Tolerance":"±5%","Inductance":"10 µH","Mounting Type":"Surface Mount","Package / Case":"1812 (4532 Metric)","Product Status":"Active","Material - Core":"Ferrite","lifecycle_stage":"unknown","Size / Dimension":"0.177\\\" L x 0.126\\\" W (4.50mm x 3.20mm)","Base Product Number":"LQH43NH","DC Resistance (DCR)":"240mOhm Max","Current Rating (Amps)":"480 mA","Height - Seated (Max)":"0.110\\\" (2.80mm)","Operating Temperature":"-40°C~125°C","Supplier Device Package":"1812","Frequency - Self Resonant":"23MHz","Current - Saturation (Isat)":"-","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b8fe98626664ecf0068858b1162f6220.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/LQH43NH100J03L","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/LQH43NH100J03L when reusing this data.
