Capacitor voltage rating is an essential specification that indicates the maximum voltage a capacitor can handle safely. It is important for anyone working with electronic or electrical circuits to understand the role of voltage rating in selecting the right capacitor for their applications.
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.
Depends on the capacitor type and environmental conditions. For electrolytic caps, they are (generally) able to withstand twice the rated voltage for 1 or 2 seconds. So, having the voltage close to its rated shouldn't be a problem. However...
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 rating of the capacitor is important because it determines the maximum voltage that the capacitor can withstand without breaking down. While choosing a capacitor that can withstand the final voltage is a good start, it's also crucial to consider the peak voltage of the ESD event.
To determine the correct voltage rating for a capacitor, the working voltage of the circuit must be considered. A common rule of thumb is to select a capacitor with a voltage rating that is at least 1.5 times higher than the circuit’s maximum voltage.

Rated voltage is what the capacitor is specified as being able to tolerate during normal operation, i.e. a 16V capacitor is (theoretically) able to tolerate being installed in a 16V circuit without undue deterioration. In practice you want to include a chunk of overhead and specify caps above your circuit voltage, but that''s what the spec means.
Also, note that the voltage rating of a capacitor is also referred to at times as the working voltage or maximum working voltage (of the capacitor). So when seeing the (maximum) working voltage specification on a datasheet, this value refers to the maximum continouous voltage that a capacitor can withstand without becoming damaged.

This is the maximum voltage that the capacitor can withstand before its dielectric material breaks down and the capacitor fails. It''s crucial not to exceed this voltage rating, as it can lead to catastrophic failure and potential safety hazards. You can find the maximum voltage rating on the capacitor''s datasheet or marking. It''s typically labeled as a voltage value, …
Capacitors intended for mains AC are designed to withstand far higher transient voltage than 1.414x the AC voltage, DC capacitors do not have this safety margin. Indeed - ever noticed that opto-couplers are rated for several kV?
require the designer to derate the voltage of SMD tantalum capacitors to 50 % of rated voltage for best results. This derating has the effect of reducing the typical estimated failure rate from around 1% per 1,000 hours to something more in the neighborhood of 5 FIT (failures in time or failures per billion hours) to 15 FIT. So the reliability improvement is very dramatic in scope. Achieving ...
3.1 Voltages 3.1.1 Rated voltage VR The rated voltage VR is the direct voltage value for which the capacitor has been designed and which is indicated upon it. For aluminum electrolytic capacitors, rated voltages of 100 V are usu-ally designated as "low voltage" and rated voltages >100 V as "high voltage". For details, refer to

withstand voltage and current surges. This is in common with all other electrolytic capacitors and is due to the fact that they operate under very high electrical stress across the dielectric. For example a 6 volt tantalum capacitor has an Electrical Field of 167 kV/mm when operated at rated voltage. OxiCap® capacitors operate at electrical field significantly less than 167 kV/mm. It is ...
Only with ceramics that have certain dielectrics. That''s certainly not a general rule. With other capacitors, except electrolytics, derating the voltage makes no difference. In electrolytics you can get a small increase in life by not going beyond 80-90% of rated voltage.
I am reading a datasheet from Murata for a ceramic capacitor. According to the datasheet: When AC voltage or pulse voltage is applied, the peak-to-peak voltage shall not exceed the rated DC voltage. I have googled a little and could not find any ceramic capacitor datasheet with surge characteristics. My question is that for example if I have a ...

Lastly, any non-X/Y rated capacitor needs to be checked if it is capable of handling the expected current ripple. Some technologies to get higher capacity at high voltage cause high ESR in this type of capacitor, which makes them unsuitable for e.g. SMPS usage. I think this is all there is to it, let me know if I forgot something or borked up.
It can be seen from the rated surge voltage value that the surge voltage tends to 2.85V, that is to say, no matter whether the rated voltage is 2.3V, 2.5V or 2.7V, the surge voltage value does not change much, which shows that the supercapacitor''s The rated voltage can be set at 2.7V. The rated voltages of 2.3V, 2.5V, and 2.7V are actually caused by differences in the …

For tantalum capacitors and ceramic capacitors, withstand voltage tests are conducted. In order to ensure reliability, the test for the capacitor requires a high-voltage power supply capable of applying a higher voltage than the standard power supply, as the test is conducted at a voltage 1.5 to 2 times the rated voltage to ensure reliability.
