特点

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).
