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_R series can be used in a digital Interface.

Resistance of BLM_R series especially grows in the

lower frequency range. Therefore BLM_R series is less

effective for digital signal waveform at low frequency

range and can suppress the ringing.
