Capacitors have a maximum voltage, called the working voltage or rated voltage, which specifies the maximum potential difference that can be applied safely across the terminals. Exceeding the rated voltage causes the dielectric material between the capacitor plates to break down, resulting in permanent damage to the capacitor.
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.
The rated voltage depends on the material and thickness of the dielectric, the spacing between the plates, and design factors like insulation margins. Manufacturers determine the voltage rating through accelerated aging tests to ensure the capacitor will operate reliably below specified voltages and temperatures.
The dielectric in the capacitor is subjected to the full potential to which the device is charged and, due to small capacitor physical sizes, high electrical stresses are common. Dielectric breakdowns may develop after many hours of satisfactory operation. There are numerous causes which could be associated with operational failures.
The Working Voltage is another important capacitor characteristic that defines the maximum continuous voltage either DC or AC that can be applied to the capacitor without failure during its working life. Generally, the working voltage printed onto the side of a capacitors body refers to its DC working voltage, (WVDC).

What about a 50V cap on 48V? I always use 63 V or 100 V capacitors when I deal with phantom power. A lot of microphones need a 48 V supply. That''s the "phantom" I am referring to. By design, the microphone pulls the supply lower than 48 V to the 24 to 36 V range, and I still don''t trust a 50 V capacitor to get the job done.
switch is closed. For breakdown rate (BDR) measure-ments, the main capacitor C1 is always charged at the same voltage and then connected to the anode for one second. If a breakdown occurs during this period, it is detected with the current transformer. The breakdown rate is defined as the fraction of attempts in which a break-down occurs.
