IDENTIFYING CAPACITOR VALUES
Capacitors will be identified by their capacitance value in pF (picofarads), nF (nanofarads), or mF (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.

Warning:
If the capacitor is
connected with incorrect
polarity, it may heat up and
either leak, or cause the
capacitor to explode.
BANDS
Electrolytic capacitors have a positive and
a negative electrode. The negative lead is
indicated on the packaging by a stripe with
minus signs and possibly arrowheads.
Also, the negative lead of a radial
electrolytic is shorter than the positive one.
