Features
The
chip
ferrite
BLM
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
is
effective
in
circuits
without
stable
ground
lines
because
BLM
does
not
need
a
connection
to
ground.
The
nickel
structure
of
the
external
electrodes
provides
excellent
heat
resistance.
BLM21SN
can
be
used
in
high
current
circuits
due
to
its
low
DC
resistance.
It
can
match
power
lines
to
a
maximum
of
8.5A
DC.
