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 small size of BLM03B series (0.6x0.3mm) is

suitable for advanced high-density mounting, and is

followed on a miniaturization of digital equipment,

or module of a functional portion.

The nickel barrier structure of the external

electrodes provides excellent solder heat resistance.
