BLM21P 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_P series can be used in high current circuits due
to its low DC resistance.
