DC-DC rail bulk decoupling and POL filter
The DFE322512F-3R3M=P2: Rated for 2 A continuous with a saturation floor of 2.6 A, it handles the ripple current of a 1.5 A POL without the inductance rolling off under load — the metal composite core keeps the saturation curve flat right up to the 2.6 A hard limit.
DCR and thermal budget at 2 A
108 mOhm max DCR means the I²R loss at 2 A is 432 mW — within the thermal budget of the 1210 body when the board has a solid copper pour under the part, but tight for a dense layout with minimal ground plane.
