Product details

What the 4.8 A rating means for your DC-DC rail

The DFE322512F-R47M=P2 is a shielded drum-core wirewound inductor from Murata's DFE322512F series, rated for 4.8 A continuous current with a maximum DC resistance of 23 mOhm. 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.
