Difference between BLM A type and B type (HG type vs HD/HB type)

A type: Impedance curve rises from low frequency range. Suppresses noise in a wide frequency range.
B type: Impedance curve rises sharply. Less damage to signal waveforms.

Difference between BLM A type and B type (HG type vs HD/HB type)

BLM_B Series has less damage to high speed signal waveform.

BLM_B Series has less damage to high speed signal waveform.

Multi Function Chip Ferrite Bead BLM□□AX Series
Excellent for Both Signal and Power Lines!

Feature

●1/2 the DC resistance than conventional type utilizing the latest technology

  • New ferrite material
  • Optimum ferrite firing condition
  • Fine piling technology
  • Advanced coil pattern design technology

●Improved stability of performance at heat shock

●Wide line - up from 10 to 1000ohm (@100MHz) useful for signal line

Advantage

●High Rated Current →Good for miniaturization of high power equipment

●Lower Voltage down at Ferrite bead →Good for Battery driven equipment by saving running voltage margin

●Higher Reliability

DC Resistance Comparison
Test Result - Heat Shock
