1.5 µH shielded power inductor — DFE252007F series
The Murata DFE252007F-1R5M=P2 is a shielded drum-core wirewound inductor in the DFE252007F series, delivering 1.5 µH ±20% in a compact 1008 (2520 Metric) footprint. Rated for 1.7 A continuous current with a saturation current floor of 2.1 A, this part uses a flat-wire winding on an iron powder core to keep DCR at 132 mOhm max — the winding geometry reduces AC losses compared to round wire in the same volume. The shielded construction limits magnetic flux leakage into adjacent circuitry, critical when the inductor sits near sensitive signal traces or RF blocks on a dense PCB.
Current handling and thermal budget
The 1.7 A rated current is the DC bias current at which the temperature rise stays within the design limit — the 2.1 A saturation current is the point where inductance drops by about 30%, so the effective usable current in a buck converter is the lower of the two, typically 1.7 A.
