AI Customer ServiceRelationship between Capacitance and ESD Resistance of Capacitors. The capacitance of the test capacitor affects the voltage that occurs on both sides of a capacitor.
AI Customer ServiceSo if a capacitor is going to be exposed to 25 volts, to be on the safe side, it's best to use a 50 volt-rated capacitor. 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).
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.
Remember that capacitors are storage devices. The main thing you need to know about capacitors is that they store X charge at X voltage; meaning, they hold a certain size charge (1µF, 100µF, 1000µF, etc.) at a certain voltage (10V, 25V, 50V, etc.). So when choosing a capacitor you just need to know what size charge you want and at which voltage.
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.
This article explains some basic parameters of capacitors – insulation resistance, DCL leakage current and breakdown voltage / withstanding voltage. Important feature of capacitor apart its capacitance is: its ability to keep the charge for some time without self-discharging due to its internal leakage (conductivity) mechanisms.
As a general rule, a properly designed capacitor of sound construction should withstand the normal 25°C dielectric withstanding flash voltage even when the temperature is 125 ° C.
