Decode 3-digit capacitor markings to capacitance values
Click to try:
The 3-digit code represents capacitance in picofarads (pF):
Example: 104 = 10 × 104 = 100,000 pF = 100 nF = 0.1 μF
| 3rd Digit | Multiplier | Example Code | Value |
|---|---|---|---|
| 0 | ×1 | 100 | 10 pF |
| 1 | ×10 | 101 | 100 pF |
| 2 | ×100 | 102 | 1,000 pF (1 nF) |
| 3 | ×1,000 | 103 | 10,000 pF (10 nF) |
| 4 | ×10,000 | 104 | 100,000 pF (100 nF) |
| 5 | ×100,000 | 105 | 1,000,000 pF (1 μF) |
| 6 | ×1,000,000 | 106 | 10 μF |
| 7 | ×10,000,000 | 107 | 100 μF |
| 8 | ×0.01 | 158 | 0.15 pF |
| 9 | ×0.1 | 159 | 1.5 pF |
