Features
The
chip
ferrite
BLM
is
designed
to
work
nearly
as
a
resistor
at
noise
frequencies,
which
greatly
reduces
the
possibility
of
resonance
and
leaves
signal
wave
forms
undistorted.
BLM
is
effective
in
circuits
without
stable
ground
lines
because
BLM
does
not
need
a
connection
to
ground.
BLM_B
series
can
minimize
attenuation
of
the
signal
waveform
due
to
its
sharp
impedance
characteristics.
Various
impedances
are
available
to
match
signal
frequency.
The
nickel
structure
of
the
external
electrodes
provides
excellent
heat
resistance.
