Obsolete — sourcing for existing BOM lines
Murata has marked the DFE201612R-H-2R2M=P2 as obsolete. Sourcing is through independent distribution channels; availability and pricing are confirmed at RFQ against the specific lot quantity.
2.2 µH shielded power inductor for DC-DC rails
This is a 2.2 µH shielded wirewound drum-core inductor in the 0806 (2016 Metric) package, rated for 1.4 A continuous with a saturation current of 1.7 A. The 154 mOhm maximum DCR sets the I²R conduction loss — at 1.4 A the self-heating is roughly 0.3 W, which must be dissipated within the 85°C ambient ceiling. The iron powder core and full shield make this inductor suitable for point-of-load regulators where radiated EMI must stay contained — the shield couples the fringe field back into the core rather than into nearby traces or the enclosure.
0806 footprint and board-fit constraints
The inductance is tested at 1 MHz, which is the typical switching frequency for a buck converter in this µH range.
