220 capacitor: 22 pF
A capacitor marked 220 has a capacitance of 22 pF. The first two digits (22) are the value in picofarads and the last digit (0) is the number of zeros to add.
220 in every unit
| Picofarads | 22 pF |
|---|---|
| Nanofarads | 0.022 nF |
| Microfarads | 0.000022 µF |
| Farads | 2.2 × 10^-11 |
How to read 220
- Take the first two digits: 22.
- Add 0 zeros: 22 pF.
- Convert: 22 pF ÷ 1,000 = 0.022 nF; ÷ 1,000,000 = 0.000022 µF.
With tolerance and voltage letters
| Marking | Meaning |
|---|---|
220J | 22 pF, ±5% |
220K | 22 pF, ±10% |
220M | 22 pF, ±20% |
1H220K | 50 V, 22 pF, ±10% |
2A220J | 100 V, 22 pF, ±5% |
Typical uses
A capacitor marked 220 is 22 pF — not 220 pF. 22 pF is the classic load capacitor for 16 MHz crystals, such as the pair next to the crystal on Arduino Uno-style boards.

FAQ
What is the value of a 220 capacitor?
22 pF: 22 × 10^0 pF = 22 pF.
What does 220J, 220K or 220M mean?
The letter is the tolerance: J = ±5%, K = ±10%, M = ±20%. The value is still 22 pF.
Can I replace a 220 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.
