The chip ferrite beads BLM series is designed to
work nearly as a resistor at noise frequencies,
which greatly reduces the possibility of resonance and
leaves signal wave forms undistorted.
BLM series is effective in circuits without stable
ground lines because BLM series does not need a
connection to ground.
BLM_B series can minimize attenuation of the
signal waveform due to its sharp impedance
characteristics. Various impedances are available to
match signal frequency.
The nickel barrier structure of the external
electrodes provides excellent solder heat resistance.
