| Marking | Tolerance | Minimum | Maximum |
|---|---|---|---|
682J | ±5% | 0.00646 µF | 0.00714 µF |
682K | ±10% | 0.00612 µF | 0.00748 µF |
682M | ±20% | 0.00544 µF | 0.00816 µF |
Other ways it's marked
On schematics and parts lists, the same capacitor appears as 6n8, 6.8 nF or 0.0068 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.
