Parametric fit for a 3.3 µH power rail
The DFEG7030D-3R3M=P3 is a 3.3 µH shielded inductor rated for 5.4 A continuous current, with a saturation current floor of 7.1 A — the margin between rated and saturation means the core holds its inductance under transient load steps up to that ceiling. DC resistance is 29 mOhm max, so at 5.4 A the I²R loss is about 0.85 W — within what a 7×6.6 mm surface-mount part can dissipate on a standard PCB with copper pours, but worth checking against your ambient derating curve. The iron powder core and full shielding keep radiated EMI low, which matters when this inductor sits near a switching node or a sensitive analog rail on the same board.
Automotive-grade deployment envelope
Inductance is tested at 100 kHz, a standard reference frequency for power inductors — the actual inductance at your switching frequency will be close to the 3.3 µH nominal within the tolerance band.
