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.","metaTitle":"Murata DFE322512F-R33M=P2 Shielded Power Inductor, 5.4 A","metaDescription":"Active Murata DFE322512F-R33M=P2 shielded wirewound inductor, 330 nH, 5.4 A, 20 mOhm DCR, 1210 package.
