AEC-Q200 qualification means this part is screened for automotive-grade thermal shock, vibration, and humidity — it belongs in engine-bay power supplies, ADAS sensor rails, or any 150°C ambient environment where a commodity inductor would drift or open. The 3.5 A rated current is the DC bias at which the temperature rise stays within the part's self-heating limit; the 4.8 A saturation current (Isat) is the point where inductance drops by 30% typically — so a 5 A load spike will saturate the core and the inductor behaves like a short until the current falls back. 30 mOhm max DCR at 25°C sets the I²R conduction loss: at 3.5 A the copper loss is 0.37 W, which drives the self-heating. In a 105°C ambient the part's 150°C absolute limit leaves about 45°C headroom for that loss — tight but workable if the PCB copper pours under the 1210 pad sink the heat. Metal composite core gives the flat saturation curve typical of these materials — inductance rolls off gradually rather than collapsing abruptly, which matters for a buck converter that must stay in regulation during a transient. ## Package and board-fit for the 1210 footprint Shielded construction contains the magnetic field within the package — adjacent traces carrying sensitive analog signals or high-impedance nodes won't couple noise from the inductor's AC ripple field. No official pin-compatible second-source or successor is recorded — the DFE32CAH_R0 series is the current generation. If a dual-source hedge is needed, a parametric search on 1.5 µH ±20%, 1210 shielded, ≥3.5 A rated, AEC-Q200 will turn up alternatives from other manufacturers for a BOM risk review.","metaTitle":"Murata DFE32CAH1R5MR0L Shielded Power Inductor, 1.5 µH","metaDescription":"Murata DFE32CAH1R5MR0L wirewound shielded inductor, 1.5 µH ±20%, 3.5 A rated, 4.8 A saturation, 30 mOhm DCR, AEC-Q200, 1210 package, -55 to 150°C.","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":"1.5 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)","DC Resistance (DCR)":"30mOhm Max","Current Rating (Amps)":"3.5 A","Height - Seated (Max)":"0.079\\\" (2.00mm)","Operating Temperature":"-55°C ~ 150°C","Supplier Device Package":"1210","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"4.8A","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 is the inductance and current rating of DFE32CAH1R5MR0L?","answer":"1.5 µH ±20% inductance, 3.5 A continuous rated current, and 4.8 A saturation current (Isat).
