Rated for 3.2 A continuous with a saturation current floor of 3.8 A, the 1 µH inductance (±20%) keeps the core from saturating under peak load transients in a point-of-load regulator. Maximum DC resistance is 42 mOhm — at 3.2 A the I²R loss is roughly 0.43 W, which the 1008 (2520 Metric) body dissipates through the board copper without exceeding the 125°C rated ambient. AEC-Q200 qualification (Grade 1, -40°C to 125°C) means this inductor passes the automotive reliability stress sequence: thermal shock, moisture resistance, mechanical shock, and vibration per the AEC-Q200 rev D test plan. The shielded construction contains the magnetic flux within the iron-powder core, reducing radiated EMI into adjacent traces — a requirement for CISPR 25 Class 5 compliance in an automotive ECU layout. ## Package footprint and board-fit checklist The flat-wire construction gives a lower profile than a comparable round-wire winding of the same current rating — the winding fills the bobbin window more efficiently, keeping the height under 1.2 mm. Supplied on tape-and-reel (embossed carrier, 8 mm wide) for automated pick-and-place; the cut-tape option is available for prototype builds.","metaTitle":"Murata DFE252012PD-1R0M=P2 Inductor, 1 µH, 3.2 A, AEC-Q200","metaDescription":"Murata DFE252012PD-1R0M=P2 shielded wirewound inductor, 1 µH ±20%, 3.2 A rated, 42 mOhm DCR, AEC-Q200, 1008 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":"DFE252012PD","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"AEC-Q200","Features":"Flat Wire","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"1 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":"DFE252012PD","DC Resistance (DCR)":"42mOhm Max","Current Rating (Amps)":"3.2 A","Height - Seated (Max)":"0.047\\\" (1.20mm)","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"2520","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"3.8A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e92a8d52b3ddff62a19e40fcd6e44560.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DFE252012PD-1R0M%3DP2/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation does Murata provide for DFE252012PD-1R0M=P2?","answer":"The part is AEC-Q200 qualified for automotive-grade reliability.
