100 capacitor: 10 pF
A capacitor marked 100 has a capacitance of 10 pF. The first two digits (10) are the value in picofarads and the last digit (0) is the number of zeros to add.
100 in every unit
| Picofarads | 10 pF |
|---|---|
| Nanofarads | 0.01 nF |
| Microfarads | 0.00001 µF |
| Farads | 1.0 × 10^-11 |
How to read 100
- Take the first two digits: 10.
- Add 0 zeros: 10 pF.
- Convert: 10 pF ÷ 1,000 = 0.01 nF; ÷ 1,000,000 = 0.00001 µF.

FAQ
What is the value of a 100 capacitor?
10 pF: 10 × 10^0 pF = 10 pF.
What does 100J, 100K or 100M mean?
The letter is the tolerance: J = ±5%, K = ±10%, M = ±20%. The value is still 10 pF.
Can I replace a 100 capacitor with a different type?
Usually, if the capacitance, voltage rating and temperature characteristic are at least as good. Check the rated voltage, and remember ceramic capacitors lose capacitance at high DC voltage.
