Inductor identity and parametric fit
The Murata DFE252010P-1R2M=P2 is a shielded drum-core wirewound inductor in the DFE252010P series, built with flat-wire windings on an iron powder core. The 1.2 µH ±20% inductance at 1 MHz test frequency and 2.4 A continuous current rating target DC-DC converter output filters and power rail smoothing in space-constrained designs. The 3.2 A saturation current (Isat) gives headroom for transient peaks before the inductance rolls off.
Lifecycle reality and sourcing posture
Sourcing is through independent surplus and inventory channels.
Package and thermal integration
The 0.039" (1.00 mm) profile suits low-clearance assemblies such as portable electronics, modules, and point-of-load regulators where board height is constrained. The iron powder core and shielded construction keep radiated EMI low, which matters when the inductor sits near sensitive analog or RF circuits on the same board.
