Capacitors will be identified by their capacitance value in pF (picofarads),
nF (nanofarads), or
μF (microfarads). Most capacitors will have their
actual value printed on them. Some capacitors may have their value
printed in the following manner. The maximum operating voltage may also
be printed on the capacitor.

Note: The letter “R” may be used at
times to signify a decimal point; as

101K
50V
The letter M indicates a tolerance of +20%
The letter K indicates a tolerance of +10%
The letter J indicates a tolerance of +5%
Maximum working voltage
(may or may not appear on the cap)
The value is 10 x 10 =
100pF, ±10%, 50V

Warning:
If the capacitor is
connected with
incorrect polarity, it
may heat up and either
leak, or cause the
capacitor to explode.
