2.2 µH with saturation headroom above the continuous rating
The DFE322520F-2R2M=P2: Rated 3.3 A continuous with a saturation current of 4.4 A — the 1.1 A headroom between the two figures means the inductor stays within its linear inductance region under most DC-DC converter peak-current transients, avoiding the sharp roll-off that collapses the output voltage.
Shielded metal-core construction for noise-sensitive rails
The shielded construction with a metal-alloy core contains the magnetic flux within the package — this keeps EMI from coupling into adjacent traces on a dense PCB, which matters when the inductor sits near a sensitive analog front-end or RF section. The 1210 footprint (3.20 x 2.50 mm body, 2.00 mm seated height) matches the standard inductor land pattern for this package class — no footprint deviation needed for pick-and-place reels.
