Capacitor Code Calculator

Instantly decode capacitor markings like "104" or "473" into real capacitance values (pF, nF, µF) or convert a value into a marking.

Quick Guide

For 3-digit codes:

  • First 2 digits = base number
  • 3rd digit = multiplier (number of zeros)

Example: 104 = 10 × 10⁴ pF = 100,000 pF = 100 nF = 0.1 µF
