Resistors are identified in Parts Lists and
steps by
their resistance value in
fl
(ohms), kfl (kilohms),
or
MH (megohms). They are usually identified by a
color
code and four or five color bands, where each
color
represents
a
number.
These
colors
(except
for the last
band,
which
indicates a resistor's "tolerance")
will be
given in
the steps in their proper order. Therefore, the
following color
code is
given for information only.
NOTE: Occasionally, a "precision" or "power" resis-
tor may have
the
value
stamped on it.

Capacitors
will
be
called
out by
their
capacitance
value
in /xF
(microfarads)
or pF
(picofarads)
and
type:
ceramic,
Mylar*,
electrolytic,
etc.
Some
capacitors
may have
their value
printed
in
the
following
man-
ner:

=

=

First
digit of
capacitor's
value:
1
Second
digit
of
capacitor's
value:
5
Multiplier:
Multiply
the
first
& second digits
by
the
proper
value from
the
Multiplier
Chart.
To
find
the
tolerance
of
the capacitor,
look
up
this letter in
the Tolerance
columns.
NOTE:
The
letter
"R"
may be used
at times to signify a
decimal
point: as in: 2R2
=
2.2 (pF
or /jlF).
