Obsolete AEC-Q200 power inductor — sourcing for existing BOM lines
The Murata DFEG12060D-3R3M=P3 is a 3.3 µH shielded power inductor from the DFEG12060D series, rated for 13 A continuous current with a maximum DC resistance of 6.3 mOhm. The saturation current is specified at 18 A, providing headroom for transient loads without a steep inductance roll-off. Qualified to AEC-Q200, this part is intended for automotive-grade power supply filtering and DC-DC converter output stages where the iron powder core handles the DC bias without saturating prematurely.
Lifecycle status and procurement path
This part is classified as Obsolete by Murata. Sourcing is through independent distribution channels; availability and pricing are confirmed at the time of RFQ against the specific BOM quantity. For a BOM line already qualified to this footprint and inductance value, the DFEG12060D-3R3M=P3 remains available via surplus and broker inventory. Lot traceability and date code documentation are provided with each shipment to support the AEC-Q200 pedigree.
Parametric fit for power-stage filtering
The 6.3 mOhm maximum DCR keeps I²R conduction losses under 1.1 W at the full 13 A rating — relevant for thermal budgeting in a surface-mount power inductor that relies on PCB copper for heat spreading. The 18 A saturation current means the inductance holds within ±20% tolerance up to that peak, which is typical for iron powder cores that exhibit a soft saturation characteristic. The shielded construction reduces radiated EMI into adjacent circuitry — a consideration for dense automotive ECU layouts where the inductor sits near sensitive analog or RF stages.
