With a tolerance letter
| Marking | Tolerance | Minimum | Maximum |
|---|---|---|---|
154J | ±5% | 0.142 µF | 0.158 µF |
154K | ±10% | 0.135 µF | 0.165 µF |
154M | ±20% | 0.12 µF | 0.18 µF |
Other ways it's marked
On schematics and parts lists, the same capacitor appears as 150n, 150 nF or 0.15 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.
