Capacitor Values:
Capacitance values in picofarads (pF) are contained in the following listing. When ordering, the first two digits represent significant figures and the last digit specifies the number of zeroes to follow. For Example 104 indicates 100,000 pF (0.1 uF) and 106 indicates 10,000,000 pF (10 uF).
