The 330 nH inductance carries a ±20% tolerance, tested at 1 MHz. ## Current ratings and saturation headroom Rated for 5.1 A continuous with a saturation current (Isat) of 7.6 A — the 49% margin between the two figures means the inductance holds within tolerance well past the rated operating current, so a 5 A rail sees no roll-off under peak transient loads. The 19 mOhm max DCR keeps I²R conduction loss at 0.49 W at the full 5.1 A rating — in a 1008 footprint with 1.2 mm seated height, that heat dissipates through the board copper, not the component body. ## Temperature range and deployment context Shielded construction contains the magnetic field within the 1008 package — this matters when the inductor sits adjacent to a sensitive ADC reference or a low-noise oscillator on a dense 2-layer board.","metaTitle":"Murata DFE252012F-R33M=P2 Shielded Power Inductor, 330 nH","metaDescription":"Murata DFE252012F-R33M=P2 shielded wirewound inductor, 330 nH ±20%, 5.1 A rated, 7.6 A Isat, 19 mOhm DCR, 1008 package, -40 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":"DFE252012F","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"-","Features":"Flat Wire","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"330 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)":"19mOhm Max","Current Rating (Amps)":"5.1 A","Height - Seated (Max)":"0.047\\\" (1.20mm)","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"2520","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"7.6A","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-R33M%3DP2/alternatives.json"},"ai":{"faq":[{"question":"What is the saturation current vs rated current margin on this inductor?","answer":"The rated current is 5.1 A and the saturation current (Isat) is 7.6 A — a 49% headroom above the continuous rating, so the inductance value holds under transient overload conditions without significant roll-off."},{"question":"What package and footprint does DFE252012F-R33M=P2 use?","answer":"The supplier device package is 2520."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/DFE252012F-R33MP2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/DFE252012F-R33MP2 when reusing this data.
