Rated 4.7 µH at 1 MHz test frequency, it carries a continuous current of 1.1 A before the DCR climb drives the temperature rise, and saturates at 1.7 A — the point where inductance drops off and the circuit sees a short. The 270 mΩ max DCR is the DC loss figure: at 1.1 A, expect about 327 mW of copper loss, which the 1008 package (2.5 × 2.0 mm footprint, 1.0 mm seated height) sinks into the board copper. ## Shielding, core, and temp range — field-fit check Shielded construction with an iron powder core means the flux is contained — no crosstalk into adjacent traces or nearby RF stages, which matters when the inductor sits next to a switching regulator on a mixed-signal board. The flat-wire winding packs more copper cross-section into the same drum height than round wire, lowering DCR for a given inductance — a design choice for higher efficiency in the same footprint.","metaTitle":"Murata DFE252010P-4R7M=P2 Shielded Inductor, 4.7 µH, 1.1 A","metaDescription":"Murata DFE252010P-4R7M=P2 shielded wirewound inductor, 4.7 µH ±20%, 1.1 A rated, 1.7 A saturation, 270 mΩ DCR, 1008 package, -40°C to +125°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":"DFE252010P","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"-","Features":"Flat Wire","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"4.7 µH","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":"DFE252010P","DC Resistance (DCR)":"270mOhm Max","Current Rating (Amps)":"1.1 A","Height - Seated (Max)":"0.039\\\" (1.00mm)","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"2520","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"1.7A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6ea2f1b32396a9c329dcca7c215c7446.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DFE252010P-4R7M%3DP2/alternatives.json"},"ai":{"faq":[{"question":"What is the saturation current vs rated current for DFE252010P-4R7M=P2?","answer":"The rated current is 1.1 A (the DC current at which the temperature rise reaches the limit), and the saturation current (Isat) is 1.7 A — the point where inductance drops by a specified percentage."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/DFE252010P-4R7MP2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/DFE252010P-4R7MP2 when reusing this data.
