That DCR figure sets the I²R loss floor — at 4.8 A the copper loss is roughly 0.53 W, which the 1210 metal-core package must dissipate without exceeding the 125°C operating ceiling. The metal composite core also delivers a saturation current of 6.7 A, meaning the inductance holds within 30% of its nominal value up to that point — useful for transient peaks in a point-of-load converter where the average load is lower than the peak. ## Sourcing and lifecycle posture Murata lists this part as Active in its product lifecycle.","metaTitle":"Murata DFE322512F-R47M=P2 Shielded Power Inductor, 4.8 A","metaDescription":"Murata DFE322512F-R47M=P2 shielded wirewound inductor, 1210 package, 4.8 A rating, 23 mOhm DCR.
