With a tolerance letter
| Marking | Tolerance | Minimum | Maximum |
|---|---|---|---|
472J | ±5% | 0.00447 µF | 0.00494 µF |
472K | ±10% | 0.00423 µF | 0.00517 µF |
472M | ±20% | 0.00376 µF | 0.00564 µF |
Other ways it's marked
On schematics and parts lists, the same capacitor appears as 4n7, 4.7 nF or 0.0047 µF.
Where it's used
Values from 1 nF to 1 µF are used for filtering, timing and signal coupling. Ceramic X7R capacitors and film capacitors are the usual choice.
