The iron powder core handles the saturation without the hard roll-off of ferrite, so the inductance holds up closer to the rated current — useful when the load transient punches above the steady-state draw. ## DCR and package — what limits the current Maximum DC resistance is 21 mOhm. At 4 A, that's an I²R loss of about 336 mW — the part self-heats, and the 125 °C ceiling on the operating range means the derating curve starts well before the current rating in a hot enclosure. The 1008 (2520 Metric) footprint with a 1.20 mm seated height fits the low-profile side of a 1.6 mm PCB — the inductor sits below the tallest passives, so it clears a typical enclosure lid. ## Active production — no end-of-life watch needed The DFE252012P series is a current catalog line, so this part is a standard BOM choice for new designs without a last-time-buy clock.","metaTitle":"Murata DFE252012P-R47M=P2 Shielded Power Inductor, 4 A","metaDescription":"Active Murata DFE252012P-R47M=P2 shielded wirewound inductor, 470 nH, 4 A, 21 mOhm DCR, 1008 package.
