That means, for example, if the actual capacitor voltage is 50V, select a capacitor rated for at least 100 V. It is a common practice in electronic component selection to derate the ceramic capacitor voltage rating by 50% to prevent explosion as well as VCC. In any electronic circuit designed with ceramic capacitors, this trend should be followed.
