BLM15B Series
s
Features
The chip ferrite beads BLM series is designed to
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
BLM_B series can minimize attenuation of the signal
waveform due to its sharp impedance characteristics.
Various impedances are available to match signal
frequency.
