Capacitor Code Conversion

Most capacitors actually have the numeric values stamped on them, however, some have alphanumeric codes. The capacitor's first and second significant number IDs and are the first and second values, followed by the multiplier number code, followed by the percentage tolerance letter code. Usually the first two digits of the code represent the significant part of the value, while the third digit, called the multiplier, corresponds to the number of zeros to be added to the first two digits. After that, the differences may show up.

The following table is for the conversion of the alphanumeric coded ceramic, and mica capacitors.
