Its 1.4 A continuous current rating and 1.9 A saturation current (Isat) give headroom for transient loads in point-of-load converters and input/output filter stages. The metal composite core keeps saturation soft and audible noise low — a common requirement for automotive infotainment and ADAS power supplies where the inductor sits near sensitive analog or RF stages. ## AEC-Q200 and 125°C — under-hood and cabin deployment The 200 mOhm maximum DCR at 25°C sets the I²R conduction loss — at 1.4 A the self-heating is 0.39 W, which the 1008 (2520 Metric) footprint dissipates into the board copper without exceeding the 125°C limit in still air.","metaTitle":"Murata DFE252012PD-4R7M=P2 Shielded Power Inductor, 4.7 µH","metaDescription":"Murata DFE252012PD-4R7M=P2 shielded wirewound inductor, 4.7 µH ±20%, 1.4 A, 200 mOhm DCR, AEC-Q200, -40°C to 125°C.
