Active production, 5.4 A continuous rating
The Murata DFE322512F-R33M=P2 is an active-production shielded wirewound power inductor in the DFE322512F series, rated for 5.4 A continuous current with an 8.5 A saturation floor. The 20 mOhm max DCR sets the I²R conduction loss — at 5.4 A the self-heating is under 0.6 W, which the 1210 metal-core package dissipates without exceeding the 125°C rated ambient.
Saturation headroom and DC bias stability
The 8.5 A saturation current (Isat) gives 57% headroom above the 5.4 A rated current — the inductance holds flat across the full operating range, which matters for a buck regulator loop that expects a constant L value for the compensation ramp. The metal composite core (Material - Core: Metal) resists hard saturation; inductance rolls off gradually rather than collapsing abruptly, so a transient overload to 7 A still leaves usable inductance for the switching cycle.
1210 footprint and reflow profile
Surface-mount termination; the shielded construction (Shielding: Shielded) contains the flux field within the core, reducing EMI coupling to adjacent sense lines or the feedback trace running under the inductor.
