Current headroom and DC resistance
The DFE322520FD-1R0M=P2: Rated 4.1 A continuous with a saturation current of 7.5 A — the 1 µH inductance holds its value well past the rated current, giving margin for transient loads like a processor core rail or a POL regulator input. The 22 mOhm max DCR keeps conduction losses under 0.4 W at full rated current, so the part stays within its self-heating budget in a 125°C ambient.
Shielded construction and 1210 footprint
Shielded drum-core construction contains the magnetic field — the leakage flux stays low, so you can place this inductor next to a sensitive analog IC or a high-gain amplifier without coupling noise into the signal path.
