1.5 µH shielded power inductor, 3 A continuous
The Murata DFE322512F-1R5M=P2 is a 1.5 µH shielded wirewound inductor rated for 3 A continuous DC current with a saturation current floor of 3.9 A. The 48 mOhm max DCR keeps conduction losses low in a 1210 (3225 metric) footprint that sits 1.20 mm high. This part belongs to the DFE322512F series, a drum-core metal-alloy construction that delivers stable inductance under DC bias — the 3.9 A saturation rating gives a 23 % headroom above the 3 A continuous rating, which means the inductor stays in its linear region during transient load steps.
Sourcing and lifecycle posture
The metal-alloy core and shielded construction make it a drop-in for power rail filtering in space-constrained designs.
The shielded construction reduces radiated EMI, which simplifies PCB layout in sensitive analog or RF sections. The metal core material handles high-frequency ripple without saturating prematurely.
