!Note
The chip ferrite beads BLM series is designed to
function 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.
The nickel barrier structure of the external
electrodes provides excellent solder heat resistance.
BLM_B series can minimize attenuation of the signal
waveform due to its sharp impedance characteristics.
Various impedances are available to match signal
frequency.
