Rated 4.6 A continuous with a saturation current floor of 6.6 A, this 330 nH part carries enough margin for a 3 A rail without the core hitting hard saturation during load transients — the 23 mOhm max DCR keeps copper losses under 0.5 W at full rated current. ## Saturation margin and thermal budget for the BOM The 6.6 A Isat spec is measured at the inductance drop point — typically a 30% roll-off from the nominal 330 nH. Below that current the inductance holds flat, so the inductor behaves linearly in a buck converter's CCM region. Shielding is full magnetic — the ferrite and iron-powder wrap contain the fringe field, so this inductor can sit next to a sensitive ADC or RF front-end without injecting noise into the ground plane. ## Active production and supply posture Tape-and-reel packaging (cut tape available) means it ships ready for pick-and-place. The 1008 footprint is a standard size, so second-source equivalents from other manufacturers exist, but no pin-compatible direct replacement is recorded from Murata.","metaTitle":"Murata DFE252012P-R33M=P2 Shielded Inductor, 330 nH, 4.6 A","metaDescription":"Murata DFE252012P-R33M=P2 shielded wirewound inductor, 330 nH ±20%, 4.6 A rated, 6.6 A saturation, 23 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":"DFE252012P","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":"DFE252012P","DC Resistance (DCR)":"23mOhm Max","Current Rating (Amps)":"4.6 A","Height - Seated (Max)":"0.047\\\" (1.20mm)","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"2520","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"6.6A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2800","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DFE252012P-R33M%3DP2/alternatives.json"},"ai":{"faq":[{"question":"What is the saturation current of DFE252012P-R33M=P2?","answer":"The saturation current (Isat) is 6.6 A, measured at the inductance drop point.
