Parametric profile and board-fit
The Murata DFE201610E-R68M=P2 is a shielded drum core wirewound inductor in the 0806 (2016 Metric) footprint, seated at 1.0 mm max height. Inductance is 680 nH at 1 MHz test frequency, ±20% tolerance. Rated current is 3.1 A, with a saturation current of 4.3 A — the inductor can handle continuous DC bias up to 3.1 A before inductance drops significantly, and the saturation headroom above the rated current means it tolerates transient peaks without hard saturation. Maximum DC resistance is 43 mOhm, which keeps I²R losses manageable at 3.1 A — about 0.41 W self-heating at full rated current, within the thermal budget of the 0806 body.
Operating temperature range spans -40°C to +125°C, covering industrial and automotive under-hood ambient conditions without derating the current rating at the high end. The metal composite core construction provides stable inductance over temperature and handles the DC bias without the saturation drift typical of ferrite cores in this footprint.
