The 670 mA figure is the DC current at which the inductance typically drops by 10% from the 8.2 µH nominal value — the real operating limit for a regulator output filter or a DC-DC input choke. The 153.6 mOhm max DCR sets the I²R loss: at 670 mA the copper loss is about 69 mW, which is manageable for a 1812 body but worth checking against the board's thermal budget if the inductor sits near other heat sources. ## Shielded ferrite core and self-resonant frequency The shielded ferrite construction keeps the magnetic field contained — useful when the inductor is placed close to sensitive analog traces or RF sections. The self-resonant frequency is 1 MHz, meaning the inductor behaves inductively up to roughly that frequency; above it the parasitic capacitance dominates and the impedance rolls off. The 8.2 µH value is tested at 1 MHz, which is within the inductive region. For switching converters running at 500 kHz to 1 MHz, this part sits in the sweet spot where the core losses are still low and the inductance holds steady. ## Board-fit and production status The 1812 (4532 Metric) footprint is a standard size for power inductors — the pick-and-place machine handles it without special nozzles, and the 2.80 mm seated height fits typical 1.6 mm PCB stack-ups with clearance.","metaTitle":"Murata LQH43PB8R2M26L Shielded Power Inductor, 8.2 µH","metaDescription":"Murata LQH43PB8R2M26L drum core wirewound inductor, 8.2 µH ±20%, 670 mA rated current, 153.6 mOhm DCR, shielded ferrite core in 1812 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":"LQH43","Package":"Tape & Reel (TR)","Ratings":"-","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"8.2 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)":"153.6mOhm Max","Current Rating (Amps)":"670 mA","Height - Seated (Max)":"0.110\\\" (2.80mm)","Operating Temperature":"-40°C~125°C","Supplier Device Package":"1812 (4532 Metric)","Frequency - Self Resonant":"1MHz","Current - Saturation (Isat)":"1.1A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3746","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the tolerance and inductance value of LQH43PB8R2M26L?","answer":"It is a 8.2 µH inductor with ±20% tolerance, tested at 1 MHz.
