The iron powder core and flat-wire winding keep the profile at 1.20 mm seated height, fitting under low-clearance components on a 2.50 x 2.00 mm footprint. ## Where does the 2.2 A rating govern the BOM decision? The 2.2 A current rating is the thermal limit at 125 °C ambient — the inductor's self-heating plus ambient must stay below the 125 °C operating ceiling. The 3 A saturation current is the point where inductance drops by 30 % typical; for a buck converter running at 1 MHz with a 2 A load, the peak inductor current stays below 2.5 A, leaving margin to saturation. The 84 mOhm DCR contributes to the converter's efficiency — at 2 A the copper loss is 0.34 W, which the 1008 footprint sinks through the PCB pad and via array. ## Active lifecycle and sourcing posture The DFE252012P series is a standard catalog line; the part is sourced through authorized and independent distribution. ## Shielded construction and temperature range The shielded drum core contains the magnetic field within the inductor body — important when the inductor sits next to a sensitive analog rail or a wireless transceiver on the same board.","metaTitle":"Murata DFE252012P-2R2M=P2 Shielded Power Inductor, 2.2 µH","metaDescription":"Murata DFE252012P-2R2M=P2 shielded drum core wirewound inductor, 2.2 µH ±20%, 2.2 A rated, 3 A saturation, 84 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":"Drum Core, Wirewound","Series":"DFE252012P","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"-","Features":"Flat Wire","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"2.2 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":"DFE252012P","DC Resistance (DCR)":"84mOhm Max","Current Rating (Amps)":"2.2 A","Height - Seated (Max)":"0.047\\\" (1.20mm)","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"2520","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"3A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2800","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DFE252012P-2R2M%3DP2/alternatives.json"},"ai":{"faq":[{"question":"How can I order DFE252012P-2R2M=P2 or check availability?","answer":"This part is sourced through authorized and independent distribution."},{"question":"What is the closest pin-compatible alternative to DFE252012P-2R2M=P2 in the same family?","answer":"No official cross-reference or second-source is recorded for this exact order code.
