The metal core and drum-core wirewound construction keep DC resistance to 95 mOhm max, which matters when you are pulling close to the current limit — the I²R loss at 2 A is under 0.4 W, manageable for a part this size. Shielded construction means the flux stays inside the core, so you can place this inductor next to sensitive analog or RF circuitry without worrying about coupling. ## Current ratings and what they mean for your rail The 2 A rated current is the DC current the inductor can carry without exceeding its temperature rise limit — typically a 40 °C rise above ambient at rated current. The 3.1 A saturation current (Isat) is where the inductance starts to drop by 30% or more. For a buck converter output, you want the peak inductor current (including ripple) to stay below Isat to avoid losing regulation. The 95 mOhm max DCR sets the conduction loss floor. At 2 A, that is 380 mW of copper loss — factor that into your thermal budget for the 0805 package. The metal core material also helps with saturation margin at high temperatures; ferrite cores lose saturation current as they heat up, but metal-composite cores hold it flatter across the -40 to +125 °C range.","metaTitle":"Murata DFE201210U-1R0M=P2 Shielded Power Inductor, 1 µH, 2 A","metaDescription":"Murata DFE201210U-1R0M=P2 shielded wirewound inductor, 1 µH ±20%, 2 A rated, 3.1 A saturation, 95 mOhm DCR, 0805 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":"DFE201210U","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"-","Features":"-","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"1 µH","Mounting Type":"Surface Mount","Package / Case":"0805 (2012 Metric)","Product Status":"Active","Material - Core":"Metal","lifecycle_stage":"unknown","Size / Dimension":"0.079\\\" L x 0.047\\\" W (2.00mm x 1.20mm)","Base Product Number":"DFE201210U","DC Resistance (DCR)":"95mOhm Max","Current Rating (Amps)":"2 A","Height - Seated (Max)":"0.039\\\" (1.00mm)","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"0805 (2012 Metric)","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"3.1A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/76b8510ac88eadb9cf689013f2c41499.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DFE201210U-1R0M%3DP2/alternatives.json"},"ai":{"faq":[{"question":"What is the saturation current for DFE201210U-1R0M=P2?","answer":"The saturation current (Isat) is 3.1 A, which is the DC current at which the inductance typically drops 30% below the nominal 1 µH value.
