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).
