The 176.4 mOhm max DCR means the copper loss at full rated current sits around 240 mW — a figure the 85°C ambient rating must absorb without exceeding the part's temperature rise. ## AEC-Q200 qualification and the deployment envelope That covers the passenger cabin, infotainment cluster, and most ADAS sensor modules, but not the engine bay or transmission controller where 125°C ambient is typical. The ferrite core material and shielded construction keep the magnetic field contained, so adjacent traces carrying 24 V or CAN bus signals see minimal coupled noise. ## Saturation current and the real-world derating rule The 1.05 A saturation current (Isat) is the DC bias level at which the inductance drops by 30% from the nominal 10 µH value. In a buck converter with 30% peak-to-peak ripple, the peak inductor current hits about 1.35 A at a 1.17 A DC load — that exceeds the Isat threshold, so the effective inductance sags and the ripple current rises further. For this reason, the part is best applied where the DC load plus half the ripple current stays below 1.05 A, or where the ripple amplitude is low enough to keep the peak under the saturation knee.","metaTitle":"Murata LQH43PH100M26L 10 µH Shielded Inductor, 1.17 A","metaDescription":"Murata LQH43PH100M26L, 10 µH ±20% shielded wirewound inductor, 1.17 A rated, 1.05 A Isat, 176.4 mOhm DCR, AEC-Q200, -40°C to +85°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","Shielding":"Shielded","Tolerance":"±20%","Inductance":"10 µH","Mounting Type":"Surface Mount","Package / Case":"Nonstandard","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":"LQH43PH","DC Resistance (DCR)":"176.4mOhm Max","Current Rating (Amps)":"1.17 A","Height - Seated (Max)":"0.110\\\" (2.80mm)","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"-","Frequency - Self Resonant":"20MHz","Current - Saturation (Isat)":"1.05A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/40059545c4eb6f6c2e95aa00aecbf1d8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the self-resonant frequency of LQH43PH100M26L and why does it matter?","answer":"The self-resonant frequency (SRF) is 20 MHz. Above this frequency the inductor behaves capacitively rather than inductively, so the part is not effective as a filter or energy storage element in circuits operating above 20 MHz. For a 500 kHz to 2 MHz switching regulator, the SRF provides ample margin."},{"question":"What compliance documentation does Murata provide for LQH43PH100M26L?","answer":"The LQH43PH100M26L is AEC-Q200 qualified, which includes the automotive-grade reliability and stress testing documentation.
