It carries a 1.2 A continuous current rating and a 2 A saturation current (Isat), with a max DC resistance of 228 mOhm. The metal core and shielded construction keep EMI from coupling into nearby traces — a common concern when routing a DC-DC converter close to a sensor front-end or RF section on a space-constrained board. ## Current rating and saturation margin The 1.2 A rated current is the DC bias at which the inductance typically drops 30% from the nominal 2.2 µH. The 2 A saturation current is the hard ceiling where inductance collapses — a converter with a 1 A peak inductor current stays well inside the linear region. The 228 mOhm max DCR at 25°C translates to about 274 mW of I²R loss at 1.2 A. In a typical 1 MHz buck converter, this is the dominant conduction loss and sets the temperature rise above ambient. Inductance is tested at 1 MHz, which aligns with the switching frequency of most modern POL converters and charge-pump circuits. ## 0805 footprint and board integration The 1.00 mm seated height keeps the profile low enough for 1.6 mm-thick PCB assemblies in card-edge or mezzanine stacks. Surface-mount reflow profile follows the standard lead-free solder curve for the metal-core construction; the part is compatible with both tape-and-reel (TR) and cut-tape (CT) packaging for prototyping or production.","metaTitle":"Murata DFE201210U-2R2M=P2 2.2 µH Shielded Inductor, 1.2 A","metaDescription":"Murata DFE201210U-2R2M=P2 drum core wirewound inductor, 2.2 µH ±20%, shielded, 1.2 A rated, 2 A saturation, 228 mOhm DCR, 0805 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":"DFE201210U","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"-","Features":"-","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"2.2 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)":"228mOhm Max","Current Rating (Amps)":"1.2 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)":"2A","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-2R2M%3DP2/alternatives.json"},"ai":{"faq":[{"question":"What is the inductance and current rating of DFE201210U-2R2M=P2?","answer":"It is a 2.2 µH shielded inductor rated for 1.2 A continuous with a 2 A saturation current.
