1.5 µH shielded power inductor for DC-DC converter rails
The Murata DFE252012F-1R5M=P2 is a 1.5 µH shielded wirewound inductor from the DFE252012F series, built with an iron powder core and flat wire winding to minimize DC resistance while handling high ripple currents. Rated at 2.7 A continuous with a saturation current of 3.8 A, this part suits point-of-load regulators and POL converters where the inductor sees both DC bias and transient peaks.
What the ratings mean for your power rail
A maximum DC resistance of 58 mOhm translates to about 0.42 W of I²R loss at the rated 2.7 A — within the thermal budget of the 1008 package when mounted on a standard PCB with adequate copper pour. The 3.8 A saturation current (Isat) is the current at which inductance drops by a specified percentage (typically 30%); for peak load transients that exceed the 2.7 A continuous rating, the inductor still delivers useful inductance up to Isat. Shielding reduces radiated EMI, which is critical when the inductor sits near sensitive analog or RF sections on the same board.
Temperature range and deployment environments
The iron powder core material maintains stable inductance over temperature and exhibits lower core loss than ferrite at high ripple frequencies — a benefit for high-efficiency DC-DC converters.
