Active production — three load-bearing specs for the BOM
The DFE252008C-3R3M=P2: Three numbers govern the fit: 3.3 µH inductance at ±20% tolerance, 850 mA continuous rated current, and 1.3 A saturation current. The 252 mOhm max DCR sets the I²R conduction loss — at 850 mA that is 182 mW, which the 1008 package must dissipate without exceeding the 85°C ambient ceiling.
Package footprint and board-fit constraints
The iron powder core handles DC bias with a softer saturation knee than ferrite — the 1.3 A Isat figure is the current at which inductance drops by 30%, not a hard collapse point. Tape-and-reel packaging supports automated pick-and-place; the 2520 supplier device package code matches standard footprint libraries.
