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 waveforms undistorted.
BLM series is effective in circuits without stable ground lines because BLM series does not need a connection to the 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.
