With a tolerance letter
| Marking | Tolerance | Minimum | Maximum |
|---|---|---|---|
475J | ±5% | 4.46 µF | 4.94 µF |
475K | ±10% | 4.23 µF | 5.17 µF |
475M | ±20% | 3.76 µF | 5.64 µF |
Other ways it's marked
On schematics and parts lists, the same capacitor appears as 4u7, 4,700 nF or 4.7 µF.
Where it's used
From 1 µF up, they filter power supplies, set timings and couple audio. Multilayer ceramic capacitors reach these values in small sizes; above about 10 µF, electrolytics are more common.
