With a tolerance letter
| Marking | Tolerance | Minimum | Maximum |
|---|---|---|---|
150J | ±5% | 0.0000142 µF | 0.0000157 µF |
150K | ±10% | 0.0000135 µF | 0.0000165 µF |
150M | ±20% | 0.000012 µF | 0.000018 µF |
Other ways it's marked
On schematics and parts lists, the same capacitor appears as 15p, 0.015 nF or 0.000015 µF.
Where it's used
Values below 1 nF are typical in radio circuits, oscillators and high-frequency filters, usually as C0G (NP0) ceramic capacitors, which stay stable with temperature.
