The Murata BLM15BD601SN1D is a multilayer ferrite bead rated 600 Ohm impedance at 100 MHz with 25 percent tolerance, a 200 mA current rating, and 650 m Ohm DC resistance. It uses a ferrite core in an unshielded, single-line 0402 imperial (1005 metric) surface-mount case measuring 1 mm x 0.5 mm x 0.5 mm. BLM15BD601SN1D is rated -55 C to 125 C, lead-free, RoHS compliant and REACH SVHC-free, and supplied on tape and reel.

Ferrite beads present low resistance at DC and rising impedance at high frequency, so they pass a supply or signal while attenuating conducted noise and preventing it from radiating off cables and traces. A 600 Ohm bead at 100 MHz targets the frequency range where switching-converter harmonics and digital clock energy cause EMC test failures. Typical placements are power-rail filtering at IC supply pins, USB and interface line filtering, clock and oscillator isolation, and antenna and RF section decoupling. The 0402 body suits smartphones, wearables, cameras, and dense embedded boards.
