Product details

Parametric fit and footprint

The DFE252012F-4R7M=P2: The iron powder core and flat-wire construction keep DC resistance at 190 mOhm max, so the 1.5 A continuous current rating is realistic for a buck regulator output filter in this footprint. Saturation current is 2.1 A, giving about 40 % headroom above the rated current before inductance rolls off — useful for transient loads where the peak current exceeds the DC average.

The shielded construction contains the magnetic field within the core, reducing EMI coupling to nearby traces on a densely populated board.

Frequently asked questions

What is the saturation current vs rated current for DFE252012F-4R7M=P2?

Rated current is 1.5 A continuous; saturation current (Isat) is 2.1 A. The 0.6 A margin means the inductor supports peak loads without hard saturation, though the inductance will begin to decline above the rated current.
