It delivers 820 nH ±20% inductance, rated for 3.6 A continuous current with a saturation current floor of 4.9 A — the point where inductance drops by 30%. With a maximum DCR of 35 mOhm, the I²R loss at 3.6 A is about 0.45 W — enough to raise the part's temperature above ambient, so the 125°C operating ceiling gives real margin in a 85°C enclosure. The iron powder core material handles the DC bias without saturating prematurely, which matters when the inductor sits between a switching regulator and a heavy load that pulls near the rated current. ## Board-fit and thermal envelope The shielded construction contains the magnetic flux, so you can place it next to sensitive analog traces or a radio front-end without coupling noise into the signal path. Operating range spans -40°C to +125°C, covering automotive under-hood and industrial ambient temperatures. The iron powder core does not exhibit the same thermal runaway risk as ferrite at high bias currents, which simplifies derating calculations for a 3.6 A rail running at 85°C ambient.","metaTitle":"Murata DFE252012F-R82M=P2 Shielded Power Inductor, 820 nH","metaDescription":"Murata DFE252012F-R82M=P2 wirewound drum core inductor, 820 nH ±20%, 3.6 A rated, 4.9 A saturation, 35 mOhm DCR, shielded, -40°C to +125°C, 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":"DFE252012F","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":"DFE252012F","DC Resistance (DCR)":"35mOhm Max","Current Rating (Amps)":"3.6 A","Height - Seated (Max)":"0.047\\\" (1.20mm)","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"2520","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"4.9A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3200","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DFE252012F-R82M%3DP2/alternatives.json"},"ai":{"faq":[{"question":"What is the saturation current of DFE252012F-R82M=P2 and why does it matter?","answer":"The saturation current (Isat) is 4.9 A. This is the DC current at which the inductance drops by 30% from its nominal 820 nH value. For a buck converter output inductor, the peak inductor current during a load transient or startup must stay below this level to prevent the inductor from behaving like a short circuit and damaging the switching FETs."},{"question":"What compliance documentation does Murata provide for this inductor?","answer":"The listing confirms the part is supplied in Tape & Reel and Cut Tape packaging.
