6 FAQs about [Capacitor withstand voltage index]
What is the rated voltage of a silicon 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.
How many volts can a series capacitor withstand?
This is because the 12.77 volt seen during the pulse (as previously derived in my answer here) is shared equally between two series capacitors. Given that the capacitors have a voltage rating of 100 volts, if they have the same value then the peak voltage withstand for two in series is 200 volts.
What happens if a capacitor exceeds rated 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.
What determines the rated voltage of a 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.
What temperature should a capacitor withstand?
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.
How are capacitors rated?
Capacitors are rated according to how near to their actual values they are compared to the rated nominal capacitance with coloured bands or letters used to indicated their actual tolerance. The most common tolerance variation for capacitors is 5% or 10% but some plastic capacitors are rated as low as ±1%.
