The 27 mOhm max DCR sets the I²R conduction loss — at 4.4 A the copper loss is about 0.52 W, which the 1008 package dissipates through the PCB copper plane under the part. Inductance is tested at 1 MHz, which matches the typical switching frequency band for DC-DC converters in this current class — the core material's permeability holds stable up through that frequency. The shielded construction with iron powder core contains the magnetic field within the package — adjacent components on a dense board see minimal flux coupling, which matters for sensitive analog or RF circuitry sharing the same power rail.","metaTitle":"Murata DFE252010F-R47M=P2 Shielded Power Inductor, 470nH","metaDescription":"Active-production shielded power inductor from Murata, 470 nH ±20%, 4.4 A continuous, 6.6 A saturation, 27 mOhm DCR. 1008 package, -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":"-","Series":"DFE252010F","Package":"Tape & Reel (TR); Cut Tape (CT)","Ratings":"-","Features":"-","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"470 nH","Mounting Type":"Surface Mount","Package / Case":"1008 (2520 Metric)","Product Status":"Active","Material - Core":"Iron Powder","lifecycle_stage":"unknown","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Base Product Number":"DFE252010F","DC Resistance (DCR)":"27mOhm Max","Current Rating (Amps)":"4.4 A","Height - Seated (Max)":"0.039\\\" (1.00mm)","Operating Temperature":"-40°C~125°C","Supplier Device Package":"-","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"6.6A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7d7daede6029ff2712f9442419a539f3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the saturation current rating and how does it relate to the continuous current?","answer":"The saturation current (Isat) is 6.6 A, which is 50% above the 4.4 A continuous current rating.
