With a tolerance letter
| Marking | Tolerance | Minimum | Maximum |
|---|---|---|---|
332J | ±5% | 0.00314 µF | 0.00347 µF |
332K | ±10% | 0.00297 µF | 0.00363 µF |
332M | ±20% | 0.00264 µF | 0.00396 µF |
Other ways it's marked
On schematics and parts lists, the same capacitor appears as 3n3, 3.3 nF or 0.0033 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.
