The metal composite core material does not exhibit the same permeability roll-off with DC bias as ferrite; the inductance holds flat to within a few percent up to the saturation current, so the output ripple current stays predictable across the load range. The ±20% tolerance is the standard bin for power-grade shielded inductors — the actual inductance at 1 MHz test frequency will fall between 0.8 µH and 1.2 µH, and the closed-loop feedback in a switching regulator compensates for that spread as long as the inductor does not saturate under the peak current. ## Surface-mount footprint and tape-and-reel supply Supplied in tape-and-reel packaging (Cut Tape and Tape & Reel options), the inductor is compatible with high-speed pick-and-place assembly; the reel quantity is the standard 3000 pieces for the 1210 body size. ## Active lifecycle — no design-in deadline The base product number DFE322512F covers the full inductance family; the suffix =P2 denotes the specific 1.0 µH ±20% variant with the metal composite core.","metaTitle":"Murata DFE322512F-1R0M=P2 Shielded Power Inductor, 1 µH","metaDescription":"Murata DFE322512F-1R0M=P2 shielded wirewound inductor, 1 µH ±20%, 3.8 A rated, 4.8 A saturation, 32 mOhm DCR, 1210 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":"DFE322512F","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"-","Features":"-","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"1 µH","Mounting Type":"Surface Mount","Package / Case":"1210 (3225 Metric)","Product Status":"Active","Material - Core":"Metal","lifecycle_stage":"unknown","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Base Product Number":"DFE322512F","DC Resistance (DCR)":"32mOhm Max","Current Rating (Amps)":"3.8 A","Height - Seated (Max)":"0.047\\\" (1.20mm)","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"1210","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"4.8A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d7b56d80319ca175368b796c3c339c0c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the saturation current for DFE322512F-1R0M=P2 and why does it matter?","answer":"The saturation current (Isat) is 4.8 A. This is the DC current at which the inductance drops by a specified percentage (typically 30% for power inductors). The 3.8 A continuous rating gives a 1 A margin below saturation, which means the inductor handles transient load steps without the inductance collapsing — critical for maintaining low output ripple in a buck converter."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/DFE322512F-1R0MP2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/DFE322512F-1R0MP2 when reusing this data.
