HOW TO USE THE CAPACITOR CODE CALCULATOR
Enter the capacitor code printed on the component, then use the calculator to convert it into a readable capacitance value. Most ceramic capacitors use a 2-digit or 3-digit code, where the first numbers are the value and the final number is the multiplier. For example, a capacitor marked 104 is 100,000 pF, which equals 100 nF or 0.1 µF.
CAPACITOR CODE EXAMPLE
A ceramic capacitor marked 104 is calculated like this:
First two digits = 10
Multiplier digit = 4
Multiplier = ×10,000
10 × 10,000 = 100,000 pF
The final value is 100 nF, or 0.1 µF.
