330 nH shielded power inductor for automotive and industrial DC-DC
The Murata DFE2HCAHR33MJ0L is a 330 nH shielded wirewound inductor from the DFE2H series, housed in a 1008 (2520 Metric) surface-mount package. It is qualified to AEC-Q200, meaning it meets the stress and reliability requirements for automotive-grade passive components. Rated for 4.9 A continuous current with a saturation current (Isat) of 5.8 A, the part delivers useful headroom for steady-state and transient loads in DC-DC converter output filters. The 21 mOhm maximum DCR keeps conduction losses low — at 4.9 A the I²R loss is about 0.5 W, manageable in the 1008 footprint without excessive temperature rise.
AEC-Q200 grade and 150°C rating for under-hood and engine-bay designs
AEC-Q200 qualification covers passive component stress tests including thermal shock, humidity bias, and vibration — the DFE2HCAHR33MJ0L is suited for automotive power trains, ADAS power supplies, and industrial systems where the ambient temperature reaches 125°C or more. The metal composite core and shielded construction keep EMI within the enclosure and support high-frequency switching up to and beyond 1 MHz test frequency.
