The 1.2 A gap between the two means the inductor retains most of its inductance well past the rated DC current — useful for designs where the load current spikes above the average but stays under the saturation knee. ## DC resistance and loss budget Maximum DCR is 40 mOhm. The iron-powder core runs cooler than ferrite at high ripple frequencies, which helps keep the DCR rise in check. ## Construction and shielding Shielded drum-core wirewound with flat-wire winding. The flat-wire geometry packs more copper cross-section into the 2.5 mm x 2.0 mm footprint than round wire, which is why the DCR stays at 40 mOhm despite the compact size. Shielding reduces radiated field coupling into adjacent traces — relevant when the inductor sits near a sensitive analog or RF section. The iron-powder core material maintains stable inductance across this band without the permeability collapse ferrites show near their Curie point.","metaTitle":"Murata DFE252010F-R82M=P2 Shielded Power Inductor, 820 nH","metaDescription":"Active Murata DFE252010F-R82M=P2 shielded wirewound inductor. 820 nH ±20%, 3.3 A continuous, 4.5 A saturation. 40 mOhm DCR. 1008 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":"DFE252010F","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"-","Features":"Flat Wire","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"820 nH","Mounting Type":"Surface Mount","Package / Case":"1008 (2520 Metric)","Product Status":"Active","Material - Core":"Iron Powder","lifecycle_stage":"unknown","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Base Product Number":"DFE252010F","DC Resistance (DCR)":"40mOhm Max","Current Rating (Amps)":"3.3 A","Height - Seated (Max)":"0.039\\\" (1.00mm)","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"2520","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"4.5A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7d7daede6029ff2712f9442419a539f3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the DFE252010F-R82M=P2's inductance and current rating?","answer":"Inductance is 820 nH ±20%, rated continuous current is 3.3 A, and saturation current is 4.5 A.
