3 Digit Capacitor Code Calculator

The 3-digit capacitor code system is a way to express the value of a capacitor using three numbers. Each number has a specific meaning.

1. The first two numbers represent the significant figures of the capacitance.
2. The third number acts as a multiplier.

If you have a capacitor marked “473“:

• The first two digits are “47”.
• The third digit is “3”.

This means the capacitance is calculated as 47×10347×103 picofarads (pF), which equals 47,000 picofarads or 47 nano-farads (nF).
