The relation between these values for different letter codes is shown in the above table. In this way by just using numbers and letters on the body of a capacitor, we can easily determine the capacitance values and tolerances of capacitors. Here 4 is first digit, 7 is second digit and 3 is the number of zeros i. Now we will see one example to understand this concept below. Letters for the specific tolerance value representation is shown in the below table. In the above figure we observed the capacitance values and tolerance for small disc or large disc capacitors can be calculated by using color code which is shown at the side of capacitors. In the case of two digit number representation tolerance is also identified. So these old capacitors are now replaced with new numbers. These colour codes are used from many years for non-polarized capacitors like disc and ceramic capacitors.Д«ut it is difficult to identify the values in the case of old capacitors. The above figure shows the Disc and Ceramic capacitors with color codes. These values can be understood by the color code table which is given at the side of capacitors in the above figure. All the above capacitors have different capacitance and tolerance values. In this each color represents a specific parameter for capacitance values, tolerance and working voltages. The capacitors which are shown in the above figure are metalized polyester capacitors with color codes.

Now let us the meaning of those letters which are used on the body of a capacitor. In this representation we see some letters or characters like J, K, N, M etc. Some voltage values are used as references for working voltages of a capacitor. The capacitor has the capacitance value, voltagetolerance and manufacturer numbers on the body of a capacitor. These color schemes color coding and colors assigned for values are explained in below. Using this color scheme we can easily identify the capacitance values, voltages and tolerance values of any capacitor. In this scheme each color of a capacitor indicates a specific capacitance value. This colour scheme for capacitors is usually called as capacitor color coding. So to avoid these problems a color scheme was introduced for capacitors like resistors. It also causes misreading of the actual capacitance and voltage values. Generally the capacitance values, working voltage and tolerance values are indicated on the body of a capacitor.Д«ut sometimes it is difficult to identify these capacitance and voltage values on the capacitor body in the case of decimal values. The capacitance of a capacitor is measured in the units of Farads. Capacitance of a capacitor is the ability of a capacitor to store maximum charge on its plates.
