It delivers 6.8 µH ±20% with a continuous current rating of 6.4 A and a saturation current floor of 8.6 A, making it suitable for DC-DC converter output filtering and EMI suppression in power trains that draw 6 A or less. AEC-Q200 qualification and a -40°C to 155°C operating range qualify it for under-hood automotive modules, engine-bay ECUs, and high-temperature industrial power supplies where ambient heat and vibration are constant. ## Sourcing reality for an obsolete line Murata has marked the DFEH10040D-6R8M=P3 as Obsolete. For a BOM line that cannot tolerate a board spin, the 10.90 mm × 10.00 mm footprint and 4.00 mm seated height define the keep-out zone. Any functional replacement must match the 6.8 µH inductance, ≥6.4 A current rating, and shielded iron-powder construction to preserve the same thermal and EMI profile. ## DC resistance and saturation margin Maximum DC resistance is 23 mOhm. At 6.4 A, the I²R loss is under 1 W, which the iron-powder core and shielded body dissipate without saturating the core — the 8.6 A saturation current provides a 34% headroom above the continuous rating, enough to handle load transients in a buck converter without inductance collapse.","metaTitle":"Murata DFEH10040D-6R8M=P3 Shielded Power Inductor, 6.8 µH","metaDescription":"Murata DFEH10040D-6R8M=P3 shielded power inductor, 6.8 µH, 6.4 A, AEC-Q200, -40 to 155°C.
