Capacitors will be identified b
y
their capacitance value in pF (picofarads), nF (nanofarads), or
μ
F
(
microfarads
)
.
Most capacitors will have their actual value printed on them.
S
ome capacitors may have their value printed in
the
f
ollowing manner. The maximum operating voltage may also be printed on the capacitor
.
