It carries a continuous current rating of 1.7 A and a saturation current of 2.1 A, with a maximum DC resistance of 140 mOhm. ## Current rating and saturation headroom for DC-DC sizing The 1.7 A rated current is the DC current at which the temperature rise from self-heating stays within the part's design limit. The 2.1 A saturation current (Isat) is the peak where inductance typically drops 30% — a buck converter's inductor ripple current plus DC bias should stay below this to avoid hard saturation and the resulting current spike through the switch FET. With 140 mOhm DCR, the I²R loss at 1.7 A is about 0.4 W — the metal core and shielded construction help conduct this heat into the PCB copper rather than trapping it in the winding. Inductance is tested at 1 MHz, which is typical for the switching frequencies in the 1-3 MHz range where this inductor is commonly used. ## Active production with automotive-grade documentation No known pin-compatible second-source — the DFE252012PD series footprint is proprietary to Murata's metal-alloy core process.","metaTitle":"Murata DFE252012PD-3R3M=P2 Shielded Power Inductor, 3.3 µH","metaDescription":"Murata DFE252012PD-3R3M=P2 drum core wirewound inductor, 3.3 µH ±20%, 1.7 A rated, AEC-Q200.
