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 aconnection 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.
