Rated current is 1.4 A, while the saturation current (Isat) is 2.1 A — the inductor can handle brief load transients up to the saturation limit before the inductance rolls off sharply. For a buck converter supplying a 1.2 V core rail at 1 A, the inductor's peak-to-peak ripple current plus the DC bias must stay below the saturation floor; a 30% ripple fraction at 1 A load leaves headroom before hitting 2.1 A. DC resistance is 195 mΩ max — at 1.4 A the I²R loss is roughly 0.38 W, which drives the temperature rise inside the 1008 case. ## Shielded construction and flat-wire winding The shield reduces radiated EMI from the magnetic field — important when the inductor sits next to a sensitive ADC or RF front-end on the same board. The flat-wire winding packs more copper cross-section into the same volume than round wire, which lowers DCR for a given inductance value compared to a conventional wirewound part of the same footprint.","metaTitle":"Murata DFE252010P-3R3M=P2 Shielded Power Inductor, 3.3 µH","metaDescription":"Murata DFE252010P-3R3M=P2 shielded wirewound inductor, 3.3 µH ±20%, 1.4 A rated, 2.1 A saturation, 195 mΩ DCR. 1008 (2520 metric) 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":"DFE252010P","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"-","Features":"Flat Wire","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"3.3 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)":"195mOhm Max","Current Rating (Amps)":"1.4 A","Height - Seated (Max)":"0.039\\\" (1.00mm)","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"2520","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"2.1A","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-3R3M%3DP2/alternatives.json"},"ai":{"faq":[{"question":"What is the inductance tolerance and test frequency for DFE252010P-3R3M=P2?","answer":"Tolerance is ±20%, and inductance is tested at 1 MHz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/DFE252010P-3R3MP2","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-3R3MP2 when reusing this data.
