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.","metaTitle":"Murata DFEG7030D-3R3M=P3 Shielded Power Inductor, 3.3 µH","metaDescription":"Murata DFEG7030D-3R3M=P3, 3.3 µH shielded power inductor, 5.4 A rated, 7.1 A saturation.

Above this level the inductance drops off sharply — the part will still conduct current but the ripple current increases, which can push the downstream regulator out of regulation or cause excess ripple on the output rail."},{"question":"What compliance documentation does Murata provide for this part?","answer":"The part is AEC-Q200 qualified, which implies RoHS and REACH compliance as standard for Murata's automotive-grade inductor lines.
