The withstanding voltage of a silicon capacitor is defined by the BV, and the rated voltage is defined by the product lifetime and operating temperature.
As an example, Murata indicates as the rated voltage the voltage at which the product is projected to have a service life of 10 years in a 100°C environment. In this example, the rated voltage is approximately 1/3 the BV. For more details, refer to the application notes "Lifetime of 3D capacitors in Murata technologies," as this relationship differs according to the BV.
