NOTES:
Part without part
number
cannot be
supplied.
Parts
marked
by
"
are
not always kept
in stock.
Their
delivery
time
may
be
longer than usual
or
they
may
be
unavailable.
The
A
mark
found on some component
parts indicates the
importance of
the
safety
factor
of
the
part.
Therefore
,
when
replacing,
be
sure
to
use parts
of
identical designation.
When
ordering
resistors, first
convert
resistance
values
into
codeform
as
shown
in
the
following examples.
Ex.
1
When
there are
2
effective digits
(any
digit
apart
from
0),
such
as
560
ohm
and
47k
ohm
(tolerance
is
shown
by
J
=
5%,
andK
10%).
