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. 1.00.05 0.50.05 (in mm) Impedance (at 100MHz/20C) (ohm) Rated Current (mA) DC Resistance (max.)
