Rated 2.6 A continuous with a saturation current floor of 3.4 A at 25°C, the part delivers a 30 % headroom above the rated current before inductance rolls off — a margin that matters when the downstream switcher hits a transient load step. DC resistance is 66 mOhm max. At 2.6 A the I²R loss is roughly 0.45 W — within the thermal budget of the 1210 body at 125°C ambient, but the board copper under the pad sets the actual temperature rise. The metal-core construction keeps core losses lower than ferrite at switching frequencies above 500 kHz, which is where this part is typically used in POL converters and point-of-load filters. The metallization pattern is a standard two-terminal chip — the pad layout matches the generic 1210 footprint, but the metal core means the part has no polarity and no exposed ferrite edge that could crack under board flex. Tape-and-reel or cut-tape options cover proto and production volumes. The metal core and shielded construction make it suitable for dense layouts where magnetic coupling to adjacent inductors or traces must be minimised. ## Sourcing and lifecycle posture Available through independent distribution channels. The tape-and-reel packaging (standard 7-inch reel) suits automated pick-and-place lines without a reel-size change.","metaTitle":"Murata DFE322512F-2R2M=P2 Shielded Power Inductor, 2.2 µH","metaDescription":"Murata DFE322512F-2R2M=P2 shielded drum core wirewound inductor, 2.2 µH ±20%, 2.6 A rated, 3.4 A Isat, 66 mOhm DCR, 1210 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":"DFE322512F","Package":"Tape & Reel (TR); Cut Tape (CT)","Ratings":"-","Features":"-","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"2.2 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)":"66mOhm Max","Current Rating (Amps)":"2.6 A","Height - Seated (Max)":"0.047\\\" (1.20mm)","Operating Temperature":"-40°C~125°C","Supplier Device Package":"1210","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"3.4A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d7b56d80319ca175368b796c3c339c0c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the saturation current and why does it matter?","answer":"Saturation current (Isat) is 3.4 A minimum. Above this current the inductance drops by 30 % or more — the inductor starts to behave like a short at the switching frequency.
