The DFE21CCNR33MELL: The metal composite core (Material - Core: Metal) and full shield mean the flux stays contained — adjacent power-stage passives or a nearby RF front-end won't see coupled noise from the inductor's fringing field, which matters when the inductor sits within 2–3 mm of a sensitive analog rail.
The continuous current rating is 4.6 A, and the saturation current (Isat) is 5.4 A — the 0.8 A headroom means the inductance holds within tolerance under peak load transients typical of a 3 A buck converter output stage.
Murata provides RoHS and REACH compliance declarations for the DFE21CCN_EL series. The part is halogen-free and meets the EU directive requirements for lead-free soldering processes.
