The 26 mOhm max DCR means at full rated current the I²R loss is about 0.53 W — the part's self-heating stays within the 125°C ceiling in a typical 85°C ambient if the PCB copper area is adequate. The 5.5 A saturation current is the point where inductance typically drops 30% — for a buck converter with 30% ripple, the peak inductor current must stay below this to avoid a hard saturation that would spike the switch current. The 4.5 A DC rating is the thermal limit; the saturation limit is higher, so the part is current-limited by temperature, not core saturation, in most designs. The metal composite core gives stable inductance over temperature and DC bias, with no air-gap fringing that would couple into adjacent traces. Surface-mount, supplied in tape and reel or cut tape — standard pick-and-place compatible. The shielded construction contains the magnetic field, so the inductor can sit next to sensitive analog or RF circuitry without crosstalk. Suitable for under-hood electronics, outdoor telecom power supplies, and motor-drive DC-DC converters where the ambient sees 105°C on a hot day. The metal core material maintains inductance across the range better than ferrite, which loses permeability above 100°C.","metaTitle":"Murata DFE201612E-R47M=P2 Shielded Inductor, 470 nH, 4.5 A","metaDescription":"Murata DFE201612E-R47M=P2 drum core wirewound inductor, 470 nH ±20%, 4.5 A rated, 5.5 A saturation, 26 mOhm DCR, 0806 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":"DFE201612E","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"-","Features":"-","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"470 nH","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)":"26mOhm Max","Current Rating (Amps)":"4.5 A","Height - Seated (Max)":"0.047\\\" (1.20mm)","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"0806","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"5.5A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3200","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":"The rated current is 4.5 A DC (thermal limit), and the saturation current (Isat) is 5.5 A.
