A Polyester Capacitor Color Code Calculator is a tool that helps decode the color bands on polyester capacitors to determine their capacitance value. It simplifies the process of reading and interpreting the color codes used by manufacturers to indicate capacitance.
Polyester capacitors typically use a 3-band color code system:
The resulting value is in picofarads (pF). To convert to nanofarads (nF), divide by 1000.
| Color | Digit | Multiplier |
|---|---|---|
| Black | 0 | ×1 |
| Brown | 1 | ×10 |
| Red | 2 | ×100 |
| Orange | 3 | ×1,000 |
| Yellow | 4 | ×10,000 |
| Green | 5 | ×100,000 |
| Blue | 6 | ×1,000,000 |
| Violet | 7 | - |
| Gray | 8 | - |
| White | 9 | - |
Use this calculator to quickly and accurately determine the capacitance of your polyester capacitors based on their color codes.
