The 5.4 A rated current is the thermal limit at the stated ambient; the 6.7 A saturation current is the point where inductance typically drops 30% — the real working current should stay below the lower of these two, and the 19 mOhm max DCR determines the I²R copper loss that heats the part. ## Metal composite core and shielded construction The metal composite core gives this inductor a soft saturation characteristic — inductance rolls off gradually rather than collapsing abruptly. That matters for DC-DC converters where the inductor sees a DC bias near the peak current: the loop remains stable even as inductance drops. The shielded construction contains the magnetic flux, reducing radiated EMI into nearby traces and components on a dense PCB. The 1210 (3225 Metric) footprint and 2.00 mm seated height fit low-profile designs like point-of-load regulators on server blades or automotive ECU boards. ## Active production — sourcing and compliance RoHS/RoHS compliance is typical for Murata's DFE series; specific certification documents are provided with the shipment upon request.","metaTitle":"Murata DFE322520F-1R0M=P2 Shielded Power Inductor, 1 µH","metaDescription":"Murata DFE322520F-1R0M=P2 wirewound shielded inductor, 1 µH ±20%, 5.4 A rated, 19 mOhm DCR, 1210 SMD.
