That headroom matters when the inductor sees transient load steps in a buck converter: the core does not saturate until the peak current exceeds 2.4 A, so the inductance holds up during the transient. The 116 mOhm max DCR sets the I²R conduction loss. At 1.8 A DC, that is 376 mW self-heating — within the 125°C rated ambient if the PCB copper area provides adequate thermal relief. Inductance tolerance is ±20%, so the minimum inductance at rated current is 1.76 µH. A downstream regulator with a minimum inductance requirement must budget for this spread. ## Metal core, 125°C ceiling — temperature stability advantage The metal composite core (Material - Core: Metal) gives this inductor a flatter inductance-versus-temperature curve than ferrite-core parts. Shielded construction (Shielding: Shielded) contains the magnetic flux, reducing radiated EMI that could couple into adjacent signal traces or the regulator's feedback path. This is a practical advantage in a dense 0806 layout where the inductor sits close to the IC. ## 0806 footprint — board-fit and procurement notes The low profile fits under a 2 mm board-to-board clearance or a low-profile enclosure. Available in Tape & Reel (TR) or Cut Tape (CT) packaging. The TR option is the standard production reel for pick-and-place; CT is for prototype or small-batch builds. No special pad geometry is required beyond the usual 0806 land pattern.","metaTitle":"Murata DFE201612E-2R2M=P2 Shielded Power Inductor, 2.2 µH","metaDescription":"Active-production shielded wirewound inductor from Murata DFE201612E series. 2.2 µH ±20%, 1.8 A rated, 2.4 A saturation, 116 mOhm DCR, 0806 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":"DFE201612E","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":"0806 (2016 Metric)","Product Status":"Active","Material - Core":"Metal","lifecycle_stage":"unknown","Size / Dimension":"0.079\\\" L x 0.063\\\" W (2.00mm x 1.60mm)","Base Product Number":"DFE201612E","DC Resistance (DCR)":"116mOhm Max","Current Rating (Amps)":"1.8 A","Height - Seated (Max)":"0.047\\\" (1.20mm)","Operating Temperature":"-40°C~125°C","Supplier Device Package":"0806","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"2.4A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0dd1f4c5608f2dd42f9b5ec429167fec.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the saturation current vs rated current for this inductor?","answer":"Rated current is 1.8 A, and the saturation current (Isat) is 2.4 A.
