Features (BLM_R Series)
The chip ferrite bead BLM series comprises ferrite
beads in the shape of a chip. This ferrite bead
generates a high impedance which at high frequencies
mainly consists of a resistance element. The BLM
series is effective in circuits without stable ground
lines because the BLM series does not need a
connection to ground.
The nickel barrier structure of the external
electrodes provides excellent solder heat resistance.
The BLM_R series can be used in a digital interface.
Resistance of BLM_R series especiallly 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.
