BLM18KG Series Ferrite Bead

New High Current Power Chip Ferrite Bead

New High Current Power Chip Ferrite Bead Murata Electronics has developed a new series of high current power ferrite beads (EIA 0603 size), which provide excellent noise suppression and low DC resistance for power supply applications. The BLM18KG series is ideal for a wide range of applications including DC power line filtering for compact mobile equipment such as Portable Navigation Devices, Cellular Phones, Personal Digital Assistants (PDAs), Notebook PCs, Audio Systems, and Hard Disk Drives.

Compared to conventional 0603 size power ferrite beads, the BLM18KG series can manage 1.5 to 2 times the rated current. This new series is also capable of handling up to 6 amps, thus comparing favorably with larger size 0805 and 1206 power and wire wound beads at a lower cost. An additional benefit of the BLM18KG series is the low DC resistance (approximately 50% less than conventional ferrite chip beads), which reduces power consumption and significantly extends battery life of portable products.

Features
  • Large DC current rating of up to 6 A
  • Offers both low DC resistance and low power loss
  • Small 0603 size (1.6 mm x 0.8 mm)
  • Wide operating temperature range of -55°C to +125°C available for extended requirements
  • Wide impedance range from 26 Ω to 600 Ω at 100 MHz
  • Flow/ Reflow solderable
  • Tape and Reel
Applications
  • Power Supplies
  • DC Power Line Filtering
