That margin matters when the DC-DC converter sees a transient load step — the inductor stays in its linear region and the output ripple doesn't spike. The 1.38 Ohm max DCR translates to roughly 0.3 W of copper loss at rated current, which the 1212 (3030 Metric) package dissipates without exceeding the 105°C upper operating limit. ## Shielded ferrite core — keeps the field off nearby traces The shielded construction and ferrite core contain the magnetic flux path, which is the main reason you reach for this part over an unshielded drum core on a dense board. On a layout with the inductor sitting next to a sensitive analog trace or a high-impedance feedback node, the shielding reduces coupled noise. The 3.00 mm × 3.00 mm footprint with a 1.50 mm seated height fits into the profile of a low-profile power stage. ## Temperature range — industrial, not automotive It does not carry AEC-Q200 qualification, so for under-hood or engine-bay designs you would need the automotive-grade Murata LQH3 series variant. The self-resonant frequency of 5 MHz means the inductor behaves as an inductor up to roughly that point — above it, parasitic capacitance takes over and the impedance rolls off.","metaTitle":"Murata LQH3NPZ680MMEL Shielded Power Inductor, 68 µH, 470 mA","metaDescription":"Murata LQH3NPZ680MMEL wirewound inductor, 68 µH ±20%, 470 mA rated, 310 mA saturation, 1.38 Ohm DCR, shielded, -40 to 105°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Inductors & Chokes"],"specifications":{"Mfr":"Murata Electronics","Type":"Wirewound","Series":"LQH3","Package":"Tape & Reel (TR)","Ratings":"-","Features":"-","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"68 µH","Mounting Type":"Surface Mount","Package / Case":"1212 (3030 Metric)","Product Status":"Active","Material - Core":"Ferrite","lifecycle_stage":"unknown","Size / Dimension":"0.118\\\" L x 0.118\\\" W (3.00mm x 3.00mm)","DC Resistance (DCR)":"1.38Ohm Max","Current Rating (Amps)":"470 mA","Height - Seated (Max)":"0.059\\\" (1.50mm)","Operating Temperature":"-40°C ~ 105°C","Supplier Device Package":"1212","Frequency - Self Resonant":"5MHz","Current - Saturation (Isat)":"310mA","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1869","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/04bb8eab2a5a3c3acc807597d1e689ae.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the saturation current of LQH3NPZ680MMEL?","answer":"The saturation current (Isat) is 310 mA.
