6 FAQs about [Capacitor terminal withstand voltage]

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.

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 is the working voltage of a capacitor?

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).

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.

Why is the voltage of a capacitor important?

That is, the value of the voltage is not important, but rather how quickly the voltage is changing. Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open. If the voltage is changing rapidly, the current will be high and the capacitor behaves more like a short.

What is the nominal value of a capacitor?

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.
