The 17 mOhm max DCR keeps I²R losses low enough that a 5 A rail dissipates under half a watt — the 1210 footprint handles that without forced air in most layouts. This is a metal-core construction, not ferrite — the core material doesn't saturate as abruptly, so the inductance roll-off past the rated current is gradual rather than a cliff. That matters when the downstream converter hits a transient and the inductor current spikes above the DC bias point. ## AEC-Q200 and the 150°C ceiling — where this part lives on the board Rated AEC-Q200, the DFE32CAHR68MR0L is qualified for automotive-grade stress — thermal shock, vibration, and bias humidity per the AEC-Q200 passive-component standard. The -55°C to 150°C operating range covers under-hood ambient plus self-heating margin; a 5 A rail at 85°C ambient still leaves headroom before the part hits its 150°C limit. ## 1210 footprint and shielded construction — layout constraints Shielded construction reduces radiated flux coupling into adjacent sense lines or feedback traces — a real concern when the inductor sits within 2 mm of a switcher's FB node. Inductance is tested at 1 MHz, which is the typical switching frequency band for point-of-load converters in the 500 kHz to 2 MHz range.","metaTitle":"Murata DFE32CAHR68MR0L Shielded Power Inductor, 680 nH, 5 A","metaDescription":"Murata DFE32CAHR68MR0L wirewound power inductor, 680 nH ±20%, 5 A rated, 7 A saturation, 17 mOhm DCR, AEC-Q200, 1210 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Inductors & Chokes"],"specifications":{"Mfr":"Murata Electronics","Type":"Wirewound","Series":"DFE32CAH_R0","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"AEC-Q200","Features":"-","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"680 nH","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)","DC Resistance (DCR)":"17mOhm Max","Current Rating (Amps)":"5 A","Height - Seated (Max)":"0.079\\\" (2.00mm)","Operating Temperature":"-55°C ~ 150°C","Supplier Device Package":"1210","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"7A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8ee68fa9654ed88426cdefb3badff48c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What compliance documentation does Murata provide for DFE32CAHR68MR0L?","answer":"The part carries AEC-Q200 qualification.
