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.
On the wafers processed with modified technology, the breakdown voltage was equal to or above 200 V, which indicates a breakdown field strength of 1×109 V/m, and has been measured for 81 % of the MIM capacitors.
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 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.
When working with a capacitor, you will typically see two values printed on the side. The first is the capacitance, obviously, and the second is a voltage. This is the “breakdown voltage,” and it is the maximum voltage that the manufacturer guarantees will not damage the capacitor. You might ask yourself, “How can a voltage damage this capacitor?”
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 voltage of a capacitor is determined by the dielectric strength times the thickness of the dielectric. Practically speaking..let's say you have two capacitors in series that are discarged. Some source of current is applied where they both become charged. One cap is 1uF and the other is 10uF. The 1uF will see ten times the voltage across it.
