This temperature range covers the under-hood and transmission-bay thermal profile — an engine ECU or transmission control module that sees 125°C ambient still has 25°C of margin before the part derates. In a dense power supply layout, the shield prevents coupling into adjacent sense lines or feedback traces — a common failure mode when an unshielded drum core sits next to a 2 MHz switching node. ## Current rating and DCR — the thermal budget decision Rated 3.5 A continuous with a saturation current (Isat) of 3.6 A and a maximum DC resistance of 33 mOhm. The narrow 0.1 A gap between the rated current and the saturation floor means the inductor's core does not begin to lose inductance until the current exceeds the continuous rating — for a buck converter output stage, the peak-to-peak ripple current plus the DC load must stay under 3.5 A to keep the inductance within the ±20% tolerance band. At 3.5 A the I²R loss through the 33 mOhm DCR is 0.4 W. A two-layer board with a solid ground pour under the part handles the dissipation; a thin flex circuit may need a wider copper pour.","metaTitle":"Murata DFE2MCAHR47MJ0L 470nH Shielded Inductor, AEC-Q200","metaDescription":"Murata DFE2MCAHR47MJ0L 470nH shielded wirewound inductor, 3.5A rated, 33mOhm DCR, AEC-Q200 qualified, -40 to +150°C.

This means the core does not saturate until the current exceeds the rated value — for a power supply design, the peak inductor current (DC load plus ripple) must stay under 3.5 A to maintain the 470 nH inductance within the ±20% tolerance. Exceeding 3.6 A causes the inductance to drop sharply, increasing ripple current and risking output voltage deviation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/DFE2MCAHR47MJ0L","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/DFE2MCAHR47MJ0L when reusing this data.
