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