With a letter or a voltage code
The letter after the code is the tolerance, and a digit-letter pair in front of it is the rated voltage on film capacitors and some ceramics:
| Marking | Meaning |
|---|---|
| 470J | 47 pF, ± 5 % |
| 470K | 47 pF, ± 10 % |
| 470M | 47 pF, ± 20 % |
| 470Z | 47 pF, +80 / −20 % |
| 2A470J | 47 pF, ± 5 %, rated 100 V |
| 1H470K | 47 pF, ± 10 %, rated 50 V |
Where you meet it
Picofarad values are used in RF circuits, oscillators and small filters, mostly as C0G (NP0) ceramics that keep their value with temperature.

Frequently asked questions
What is a 470 capacitor?
Read as a code, 470 is 47 pF: 47 followed by no zeros, in picofarads. Some makers of small ceramic discs print the value written out instead, and then 470 means 470 pF.
What is 470 in µF and nF?
470 = 47 pF = 0.047 nF = 0.000047 µF.
What do 470J, 470K and 470M mean?
The same capacitance, 47 pF, with a tolerance of ± 5 % (J), ± 10 % (K) or ± 20 % (M).
