DC resistance is 31.2 mOhm max, so at 1.41 A the I²R loss is about 62 mW — negligible in most power-stage layouts, but worth checking if the inductor sits in a tightly enclosed module with no airflow. Self-resonant frequency is 100 MHz, which means the inductive impedance holds up well into the tens of MHz before parasitic capacitance starts to dominate — fine for buck converters switching at 1–2 MHz, but not the right part for a 50 MHz RF bias tee. ## Package and temperature fit for a 24/7 line 1812 (4532 Metric) body, 4.50 x 3.20 mm footprint, seated height 2.80 mm max — the 1812 land pattern is standard, and the height keeps it under most low-profile heatsinks or enclosure lids. Operating temperature range -40 to +125 °C covers industrial and automotive under-hood ambient; the ferrite core material is stable across that band, though inductance tolerance is ±30% over temperature and current. Shielded construction means the magnetic field is contained within the ferrite shell — no crosstalk into adjacent traces or sensitive analog loops on the same board layer.","metaTitle":"Murata LQH43PB1R0N26L Shielded Wirewound Inductor, 1 µH","metaDescription":"Murata LQH43PB1R0N26L shielded drum-core wirewound inductor, 1 µH, 1.41 A rated, 3.4 A saturation, 31.2 mOhm DCR, 1812 SMD, -40 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)","Ratings":"-","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±30%","Inductance":"1 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":"LQH43PB","DC Resistance (DCR)":"31.2mOhm Max","Current Rating (Amps)":"1.41 A","Height - Seated (Max)":"0.110\\\" (2.80mm)","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"1812 (4532 Metric)","Frequency - Self Resonant":"100MHz","Current - Saturation (Isat)":"3.4A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3150","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/aa37ec466e7678f87545fa5f8b803d57.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the saturation current of LQH43PB1R0N26L?","answer":"The saturation current (Isat) is 3.4 A, well above the 1.41 A continuous current rating — the core saturates gradually, so brief overloads up to that level are tolerated without hard failure."},{"question":"What compliance documentation does Murata provide for LQH43PB1R0N26L?","answer":"Murata provides RoHS and REACH compliance documentation for the LQH43 series.
