Selecting a capacitor with a working voltage at least 1.5 times or twice the voltage specified for a given circuit is always safe. The most common working voltages for standard capacitors are 6.3V, 10V, 16V, 25V, 30V, 35V, 40V, 50V, 63V, 100V, 160V, 200V, 250V, 400V, 450V, 500V and 1000V.
Chart1: CAPACITOR MARKING CODE STANDARDIZED BY THE ELECTRONIC INDUSTRY ALLIANCE (EIA) The voltage rating on a capacitor indicates the maximum voltage it can safely handle. This parameter is ensuring safety and performance, as it prevents over-voltage failures that can damage both the capacitor and the surrounding circuitry.
As the capacitor vendors have made smaller and smaller components, they have had to compromise on the materials used. To get the needed volumetric efficiencies in the smaller sizes, they have had to accept worse voltage coefficients. Of course, the more reputable manufacturers do their best to minimize the adverse affects of this trade-off.
Most small ceramic capacitors are rated for 50V or 100V which is high enough above typical modern solid-state circuit voltages that the capacitor voltage is not of great importance. Unless you are working with higher voltage circuits. For some values of "small"! Like other components, ceramic capacitors have a voltage rating.
The working voltage is one more important characteristic of all capacitor characteristics. The maximum amount of voltage which is applied to a capacitor without failure during its working life is called as working voltage (WV). This working voltage is expressed in terms of DC and also it is printed on the body of a capacitor.
The temperature coefficient codes which are used for a capacitor are in most of the cases the standard codes given by the EIA. But there are other temperature coefficient codes which are used in the industry by different manufacturers, especially for capacitors including film and ceramic type of capacitors.
