Parametric profile for BOM-fit check
The DFE252010R-H-2R2M=P2: Rated for 1.7 A continuous with a 126 mOhm max DCR, and a saturation current of 2.1 A — the DCR is the thermal limiter in steady-state, while Isat governs peak transient current before inductance drops by 30%. The iron powder core and full shield contain the flux field, making this part suited for DC-DC converter input/output filters where radiated EMI must stay within the board footprint.
Lifecycle reality and sourcing posture
Available through independent surplus and broker channels; each reel is lot-specific and graded on date-code consistency and original packaging condition at the time of RFQ.
