Capacitor Alphanumeric Code

Third column indicates the tolerance value sub columns for above and below 10pf of the capacitor. The capacitance can range from 1pico factor to 1 farad.

Capacitor Codes

In many instances where the capacitor is small no voltage coding is provided and care must be taken when using a capacitor without any knowledge of its working voltage.

Capacitor alphanumeric code. If you are building an ac circuit look for a capacitor rated specifically for vac. This coding is used widely in various types of capacitors especially for the capacitors which have enough space to write alphanumeric codes. The capacitor color code for ceramic capacitors is shown in the above figure in which first column represents different types of colors the second column represents the value indicated by a specific color.

The working voltage for a capacitor is very important and therefore this parameter is often marked on capacitors and particularly in situations where there is space for alphanumeric coding. They come in many sizes shapes values and ratings. Many different manufacturers worldwide produce them and not all play by the same rules.

Additionally capacitors that are polarizedthey have a and a leadalso carry a polarization marking. Capacitor colour codes generally the actual values of capacitance voltage or tolerance are marked onto the body of the capacitors in the form of alphanumeric characters. If there is no symbol at all reserve the cap for low voltage circuits only.

Capacitors are routinely marked with at least their capacitance value. Working voltage code of capacitors. However when the value of the capacitance is of a decimal value problems arise with the marking of the decimal point as it could easily not be noticed resulting in a misreading of the actual capacitance value.

The alphanumeric code consists of two digits plus a letter in its proper form always an si prefix before between or after these. Capacitor code information this table is designed to provide the value of alphanumeric coded ceramic mylar and mica capacitors in general. See below if you suspect your capacitor uses a code for voltage a single letter or one digit and one letter.

The value is found by replacing the letter with a decimal point moving the letter to the end and adding the appropriate unit in this case farads f. Many capacitors are also marked with value tolerance notation and a breakdown voltage. Every capacitor has colors or alphanumeric characters on the body which indicates the nominal capacitance value of the capacitor.

Most capacitors actually have the numeric values stamped on them however some are color coded and some have alphanumeric codes. The working voltage of a capacitor is one of its key parameter. The capacitors 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.

Mica capacitor value codes 1st value. The tolerance codes used in the capacitors are similar to the codes used in the resistors. Capacitor working voltage codes.

The capacitance can range from 1pico factor to 1 farad.
