The self-resonant frequency of 20 MHz sets the upper bound for inductive behaviour; above this frequency the impedance turns capacitive, which matters when the inductor is used in a DC-DC output filter or a bias-tee network. ## Unshielded construction and board-fit note Unshielded magnetic circuit means the flux field extends beyond the component body — adjacent traces carrying high-frequency signals or sensitive analog lines should be kept at least one part-width away to avoid unwanted coupling. The ferrite core material supports the inductance stability across the operating temperature range.","metaTitle":"Murata LQH43CN150K03L 15 µH Unshielded Wirewound Inductor","metaDescription":"Active-production 15 µH unshielded wirewound inductor from Murata's LQH43 series. 570 mA rated, 320 mOhm DCR, 20 MHz SRF. 1812 footprint.","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":"-","Q @ Freq":"-","Shielding":"Unshielded","Tolerance":"±10%","Inductance":"15 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":"LQH43CN","DC Resistance (DCR)":"320mOhm Max","Current Rating (Amps)":"570 mA","Height - Seated (Max)":"0.110\\\" (2.80mm)","Operating Temperature":"-40°C~85°C","Supplier Device Package":"1812","Frequency - Self Resonant":"20MHz","Current - Saturation (Isat)":"-","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/285342e99fdeeb4e955f855a995fa4ac.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LQH43CN150K03L/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to LQH43CN150K03L in the LQH43 family?","answer":"The LQH43 series includes multiple inductance values in the same 1812 footprint — e.g., 10 µH, 22 µH, or 33 µH variants — but no official cross-reference or second-source is published. If the BOM calls for 15 µH at 570 mA, the LQH43CN150K03L is the Murata order code that matches that inductance and current rating."},{"question":"What compliance documentation does Murata provide for LQH43CN150K03L?","answer":"Murata Electronics provides RoHS and REACH compliance data for the LQH43 series inductors.
