It is designed for surface-mount power supply filtering, typically on the output side of a buck converter where the inductor stores and releases energy to smooth the voltage rail. Rated for 1.4 A continuous current with a saturation current (Isat) of 1.8 A — the inductance value holds stable up to the saturation limit, above which the core saturates and the inductance drops sharply. The 204 mOhm maximum DC resistance sets the I²R conduction loss; at 1.4 A the self-heating from DCR alone is about 0.4 W, which must be dissipated through the PCB copper. ## Obsolete — sourcing through independent channels Murata has marked the DFE201208S-2R2M=P2 as obsolete. ## 0805 footprint and thermal integration The low profile suits tight board stacks in portable or embedded designs where the component height is constrained by an enclosure or a second PCB above. The metal core material improves saturation current density over ferrite but has higher core loss at high switching frequencies — above 2–3 MHz the AC loss may dominate the thermal budget, so the 1 MHz test frequency for the inductance value is a good reference point for the intended switching range.","metaTitle":"Murata DFE201208S-2R2M=P2 2.2 µH Shielded Power Inductor","metaDescription":"Murata DFE201208S-2R2M=P2 2.2 µH shielded wirewound inductor, 1.4 A rated, 1.8 A Isat, 0805 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Inductors & Chokes"],"specifications":{"Mfr":"Murata Electronics","Type":"Drum Core, Wirewound","Series":"DFE201208S","Package":"Tape & Reel (TR)","Ratings":"-","Features":"-","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"2.2 µH","Mounting Type":"Surface Mount","Package / Case":"0805 (2012 Metric)","Product Status":"Obsolete","Material - Core":"Metal","lifecycle_stage":"unknown","Size / Dimension":"0.079\\\" L x 0.047\\\" W (2.00mm x 1.20mm)","Base Product Number":"DFE201208S","DC Resistance (DCR)":"204mOhm Max","Current Rating (Amps)":"1.4 A","Height - Seated (Max)":"0.031\\\" (0.80mm)","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"0805","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"1.8A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e4142c36ed0a01a9c998cc018f385fab.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DFE201208S-2R2M%3DP2/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the DFE201208S-2R2M=P2 and how is it quoted?","answer":"Submit an RFQ for the quantity needed and the desk will return a quote with date codes and pricing."},{"question":"What is the saturation current of this inductor and why does it matter?","answer":"The saturation current (Isat) is 1.8 A. Above this current the metal composite core saturates and the inductance drops below the 2.2 µH value.
