330 nH shielded inductor with 5.1 A continuous rating
The Murata DFE252012F-R33M=P2 is a shielded drum-core wirewound inductor from the DFE252012F series, built on an iron powder core with flat-wire construction. The 330 nH inductance carries a ±20% tolerance, tested at 1 MHz.
Current ratings and saturation headroom
Rated for 5.1 A continuous with a saturation current (Isat) of 7.6 A — the 49% margin between the two figures means the inductance holds within tolerance well past the rated operating current, so a 5 A rail sees no roll-off under peak transient loads. The 19 mOhm max DCR keeps I²R conduction loss at 0.49 W at the full 5.1 A rating — in a 1008 footprint with 1.2 mm seated height, that heat dissipates through the board copper, not the component body.
Temperature range and deployment context
Shielded construction contains the magnetic field within the 1008 package — this matters when the inductor sits adjacent to a sensitive ADC reference or a low-noise oscillator on a dense 2-layer board.
