Features
The chip ferrite beads BLM series is designed to
work nearly as a resistor at noise frequencies,
which greatly reduces the possibilit
y
o
f resonance and
lea
v
e
s signal wa
v
e for
m
s undistorted.
BLM series is effecti
v
e
i
n circuits without stable
ground lines because BLM series does not need a
connection to ground.
BL
M
_
B series can minimi
z
e
a
ttenuation of the
signal wa
v
e
form due to its sharp impedance
characteristics.
V
a
rious impedances are a
v
a
ilable to
match signal frequenc
y
.
