Features
1.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.
2.The
nickel
barrier
structure
of
the
external
electrodes
provides
excellent
solder
heat
resistance.
3.BLM31KN
series
can
be
used
in
high
current
circuits
due
to
its
low
DC
resistance.
It
can
match
power
lines
to
a
maximum
of
6A
DC.
Extended
the
spec
of
former
BLM31PG/41PG
series.
Got
larger
rated
current
at
same
impedance
value
of
BLM31PG/41PG
series.
