Murata EMIFIL® BLM15 Series Chip Ferrite Beads

Murata EMIFIL® (Inductor type) BLM15 Series Chip Ferrite Beads are part of Murata's noise suppression product line.  These chip ferrite beads have simple structures and have been downsized into a smaller, easy-to-use component capable of addressing noise suppression in small portable devices such as mobile phones, mobile audio players, and portable game consoles, which have become smaller and operate at increasingly higher frequency.  The BLM15BX series operates at higher frequencies and is used in high-speed signal lines.  The BLM15PX is used in power supplies.

Features

  • Do not require connection to ground
  • Nickel-barrier structure of the external electrodes provides excellent solder heat resistance


The BLM_B series generates an impedance from relatively low frequencies.  The BLM_B series is suitable for advanced high-density mounting, and because of a newly developed ferrite material, the BLM15BX is able to achieve lower DC resistance and larger rated current than comparable BLM series.

Size: 0402
