That means the factory has stopped production — no new manufacturing runs. ## 1 µH, 3.1 A — what the current ratings mean for the load Rated current is 3.1 A and saturation current (Isat) is 3.4 A. The 3.1 A figure is the DC current at which the inductance typically drops by a specified amount — usually around 30% for this construction. The 3.4 A Isat is the hard magnetic saturation point; beyond it the inductor behaves like a short. In a DC-DC converter feeding a 3.3 V rail at 2.5 A continuous, this part has margin. The 49 mOhm max DCR sets the I²R copper loss — at 3.1 A that's about 0.47 W, which the 1008 body dissipates without exceeding the 85°C ambient ceiling. ## Shielded drum-core with flat-wire winding The DFE252012R series uses a shielded drum-core construction with an iron powder core and flat-wire winding. The shield contains the magnetic field — critical when the inductor sits near sensitive analog or RF circuitry on the same PCB. That low profile suits tight board stacks in portable or embedded power modules.","metaTitle":"Murata DFE252012R-H-1R0M=P2 Shielded Power Inductor, 1 µH","metaDescription":"Murata DFE252012R-H-1R0M=P2 shielded wirewound inductor, 1 µH ±20%, 3.1 A rated, 3.4 A sat, 49 mOhm DCR.
