The BLM15HD182SN1D delivers 1.8 kOhms impedance at 100 MHz, which is the typical noise frequency band for switching regulators and digital clock harmonics. At 200 mA continuous current, the 2.2 Ohm DC resistance drops 440 mV across the bead — budget that into the rail voltage margin for the downstream load.
The 0402 package footprint (1.00 mm x 0.55 mm) fits dense PCB layouts where trace routing space is tight.
