!Note
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
ground lines because BLM series does not need a
connection to ground.
The nickel barrier structure of the external
electrodes provides excellent solder heat resistance.
BLM_A series generates an impedance from the
relatively low frequencies. Therefore BLM_A series is
effective in noise suppression in a wide frequency
range (30MHz to several hundred MHz).
