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.
The BLM series is effective in circuits without stable
ground lines because the BLM series does not need a
