22 µH, 6 A, AEC-Q200 — what the ratings mean for the BOM
The DFEG12060D-220M=P3 is a 22 µH shielded power inductor from Murata's DFEG12060D series, rated for 6 A continuous with a saturation current of 6.5 A. The 35 mOhm max DCR sets the I²R conduction loss — at 6 A the self-heating is roughly 1.26 W, which the iron powder core and nonstandard 13.00 mm x 12.60 mm footprint must dissipate without exceeding the 125 °C operating ceiling. AEC-Q200 qualification means this inductor passed the automotive passive-component stress tests: thermal shock, vibration, mechanical shock, solderability, and moisture resistance per the AEC-Q200 rev D specification.
Shielded construction and core material
The shielded construction contains the magnetic flux within the core, reducing radiated EMI to adjacent traces and components — critical in dense automotive ECU layouts where a buck converter's inductor sits next to a CAN transceiver or MCU. The iron powder core material handles high DC bias without saturating abruptly; the 6.5 A saturation current is only 8 % above the 6 A rated current, so the inductance roll-off starts well before the peak load.
Obsolete — sourcing reality for the DFEG12060D-220M=P3
Murata has marked the DFEG12060D-220M=P3 as obsolete. No official successor order code is recorded in the lifecycle data. No pin-compatible drop-in replacement from Murata's current DFEG12060D family is documented; a parametric search for 22 µH, 6 A+, shielded, AEC-Q200 inductors in a similar footprint will identify functional alternatives, but each requires board-level validation.
