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.
In practice, the commonly rated DC voltages of capacitors are 10 V, 16 V, 25 V, 35 V, 50 V, 63 V, 100 V, 160 V, 250 V, 400 V, and 1000 V. These voltages are mentioned on the body of the capacitor. The capacitors can be connected in series connections when they are to be used for higher voltage.
There are different types of representations for the voltage rating of these capacitors. Sometimes it is written clearly on the enclosure of the capacitor with its unit. For some disk capacitors, it is represented by a single underline after the capacitance value. This underline shows 100 V as the maximum working voltage.
Capacitors are rated according to how near to their actual values they are compared to the rated nominal capacitance with coloured bands or letters used to indicated their actual tolerance. The most common tolerance variation for capacitors is 5% or 10% but some plastic capacitors are rated as low as ±1%.
So if a capacitor is going to be exposed to 25 volts, to be on the safe side, it's best to use a 50 volt-rated capacitor. Also, note that the voltage rating of a capacitor is also referred to at times as the working voltage or maximum working voltage (of the capacitor).
In another, 50 volts may be needed. A capacitor with a 50V rating or higher would be used. This is why capacitors come in different voltage ratings, so that they can supply circuits with different voltages, fitting the power (voltage) needs of the circuit.
