The 138 mOhm maximum DCR keeps I²R losses manageable in a 1.8 A rail — at full load the self-heating is roughly 0.45 W, which the 0805 metal-core construction dissipates into the board copper without exceeding the 125°C temperature ceiling. ## Saturation headroom and temperature grade The 2.1 A saturation current sits 16% above the 1.8 A continuous rating — this headroom means the inductance holds its value under transient load steps common in point-of-load converters, where the peak current can exceed the DC bias for tens of microseconds. ## 0805 footprint and reel packaging Supplied on tape and reel (cut tape available), the shielded construction means adjacent inductors on the same reel can be placed without mutual coupling concerns during reflow.","metaTitle":"Murata DFE21CCN2R2MELL Shielded Power Inductor, 2.2 µH","metaDescription":"Murata DFE21CCN2R2MELL drum core wirewound inductor, 2.2 µH ±20%, 1.8 A, 138 mOhm DCR, shielded, 0805 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":"DFE21CCN_EL","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":"0805 (2012 Metric)","Product Status":"Active","Material - Core":"Metal","lifecycle_stage":"unknown","Size / Dimension":"0.079\\\" L x 0.047\\\" W (2.00mm x 1.20mm)","DC Resistance (DCR)":"138mOhm Max","Current Rating (Amps)":"1.8 A","Height - Seated (Max)":"0.031\\\" (0.80mm)","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"0805","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"2.1A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ca1ecd80c04adbf6ab1ea5843bf048f4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the saturation current vs rated current on this inductor?","answer":"The continuous current rating is 1.8 A, while the saturation current (Isat) is 2.1 A.
