Saturation current is 2.1 A, giving about 40 % headroom above the rated current before inductance rolls off — useful for transient loads where the peak current exceeds the DC average. The shielded construction contains the magnetic field within the core, reducing EMI coupling to nearby traces on a densely populated board.","metaTitle":"Murata DFE252012F-4R7M=P2 Shielded Power Inductor, 4.7 µH","metaDescription":"Murata DFE252012F-4R7M=P2 drum core wirewound inductor, 4.7 µH ±20%, 1.5 A rated, 2.1 A saturation, 190 mOhm DCR, shielded, -40 to +125°C.
