Active production, metal-core shielded inductor for power rails
The Murata DFE201610E-R33M=P2 is an active-production drum-core wirewound inductor from the DFE201610E series, shielded with a metal composite core for high saturation current in a compact 0806 footprint.
Current rating and saturation headroom
Rated for 4 A continuous with a saturation current of 5.5 A, this inductor handles transient peaks without hard saturation — the metal core keeps the inductance rolloff gradual above the rated current. The 26 mOhm max DCR keeps I²R losses under 0.42 W at full rated current, which the 0806 body and 1.00 mm seated height can dissipate in still air at 85°C ambient.
Its ±20% tolerance is typical for shielded power inductors in DC-DC converter output stages — the inductance value at 1 MHz test frequency aligns with the switching frequency of most buck converters in this current class.
