Rated 3 A continuous with a 3.4 A saturation current, it carries a 50 mOhm max DCR — a figure that sets the conduction loss in the power path and drives the thermal rise at full load. The -40°C to 150°C operating range covers the engine bay temperature band, including the hot soak after shutdown. ## Current rating, saturation, and DCR: what they mean for your DC-DC stage The 3 A continuous current rating is the thermal limit under the worst-case ambient — the inductor's internal temperature rise stays within the material limit at that load. The 3.4 A saturation current (Isat) is higher, meaning the inductance holds within tolerance until just past the rated current; a transient spike to 3.4 A does not cause a hard roll-off. 50 mOhm max DCR at 25°C produces an I²R loss of 0.45 W at 3 A — this is the heat the inductor dumps into the board. Accounting for the DCR temperature coefficient (copper rises about 0.4%/°C), the actual resistance at 125°C ambient is roughly 70 mOhm, pushing loss to 0.63 W. The designer's thermal budget must absorb this. ## Active production — sourcing and compliance posture Marked active in production — there is no NRND or EOL notice on this order code. The DFE2HCAH1R0MJ0L is sourced to order against BOM quantities through authorized and independent distribution; current pricing and availability are confirmed at RFQ time. For BOM hedge, a parametric search on 1 µH, 3 A+, 1008 shielded, AEC-Q200 yields the same-series siblings.","metaTitle":"Murata DFE2HCAH1R0MJ0L: 1 µH Shielded Power Inductor","metaDescription":"Murata DFE2HCAH1R0MJ0L: 1 µH shielded wirewound inductor, 3 A rated, AEC-Q200 qualified.
