One hundred picofarads capacitance.
Ceramic capacitor 102 value.
Many capacitors are also marked with value tolerance notation and a breakdown voltage.
Ceramic capacitors encoding consists 1 3 digits.
For example if the marking is 101p the actual capacitance is no less than 100 pf but may be as much as 200 pf.
The 3 digit capacitor code 102 stands for 1 nf in words.

For electrolytic capacitors simply capacitance values are written on them.
The 3 digit capacitor code 101 stands for 100 pf in words.
For codes s x and z the actual capacitance may be as much as 20 below the stated value or as much as 50 40 or 80 over the stated value.

If the marking is 101z the capacitance is between 80 pf and 180 pf.
Capacitors are routinely marked with at least their capacitance value.
Common ceramic capacitor tags capacitor 108 0 1 pf capacitor 158 0 15 pf capacitor 228 0 22 pf capacitor 338 0 33 pf capacitor 478 0 47 pf.
The first is used with small ceramic capacitors and appears as a single.

Encoding for ceramic capacitors.
Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them.
The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.
If the capacitor code consist only 1 or 2 digits it is simply their capacitance.
