560 nH shielded power inductor for DC-DC rail filtering
The Murata DFE18SANR56ME0L is a 560 nH shielded power inductor from the DFE18SAN series, built on a metal-alloy core that handles 2.2 A continuous with a DCR ceiling of 84 mOhm. The saturation current floor is 3 A, so the inductor holds its inductance well into overload before the core rolls off — useful for a buck converter that sees transient spikes above the steady-state load.
0603 footprint and board-fit constraints
The shielded construction contains the magnetic field within the package, so adjacent traces on a dense board see less EMI coupling than an unshielded drum-core inductor would allow.
Temperature grade and operating envelope
The ±20% tolerance on the 560 nH nominal value is typical for power-grade inductors; the actual inductance at the rated 2.2 A will be lower due to DC bias, but the 3 A saturation floor ensures the inductance drop stays controlled under the full load current.
