Product details

3.3 µH shielded power inductor for DC-DC rail filtering

The Murata DFE252012F-3R3M=P2 is a 3.3 µH shielded power inductor in the DFE252012F series, rated for 1.8 A continuous current with a saturation current floor of 2.8 A. The 135 mOhm maximum DCR sets the conduction loss — at 1.8 A the I²R loss is 437 mW, which factors into the thermal budget for the surrounding regulator and board copper. Shielded construction with an iron powder core contains the magnetic field, reducing EMI coupling into adjacent traces and components on a dense PCB.

Surface-mount termination supports standard reflow soldering; the iron powder core material handles the thermal cycling without cracking.

Frequently asked questions

What is the saturation current rating for DFE252012F-3R3M=P2?

The saturation current (Isat) is 2.8 A, providing headroom above the 1.8 A continuous rating for transient peaks in a buck converter or POL regulator.
