Ceramic Capacitor Code Calculator
Enter the 3-digit code:
A Capacitor Code to Value Calculator is a tool that interprets the numeric code printed on ceramic capacitors and translates it into the actual capacitance value in units like picofarads (pF), nanofarads (nF), or microfarads (µF). Capacitors are often labeled with a three-digit code where the first two digits represent significant figures and the third digit is a multiplier.
For example:
- A capacitor marked with 104 would mean 10 followed by 4 zeros in picofarads, resulting in 100,000 pF, or 100 nF.
- A code 472 would mean 47 followed by 2 zeros, resulting in 4700 pF or 4.7 nF.
Here’s how it works:
- Significant Figures: The first two digits represent the significant part of the capacitance value.
- Multiplier: The third digit is a power of ten multiplier that you apply to the significant figures.
Example Codes and Values
- 101 → 100 pF (10 followed by 1 zero)
- 103 → 10,000 pF or 10 nF (10 followed by 3 zeros)
- 224 → 220,000 pF or 220 nF (22 followed by 4 zeros)
