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.
Adequate safety margins should be used when choosing capacitor voltage ratings for an application, with higher safety factors for critical reliability. General guidelines include: Minimum 2x margin between working voltage and rated voltage for general purpose capacitors. Minimum 10-20% margin for capacitors in power supplies and power conversion.
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).
The other use of the term "breakdown" in electronics is for breakdown voltages in diodes. For capacitors in series, 1/C [total] = 1/C + 1/C + 1/C +... For caps in parrallel, C [total] = C + C + C + ... The current and v0ltage are related by i = C (dV/dt), which are just derived from the equation Q=CV.
The nominal value of the Capacitance, C of a capacitor is the most important of all capacitor characteristics. This value measured in pico-Farads (pF), nano-Farads (nF) or micro-Farads (μF) and is marked onto the body of the capacitor as numbers, letters or coloured bands.
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.
