Features (BLM_P Series)
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
The BLM_P series can be used in high current circuits
due to its low DC resistance. It can match power lines
to a maximum of 6A DC.
