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.
- The first two numbers represent the significant figures of the capacitance.
- 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).
