We typically use a test voltage that is twice the working voltage rating of the device, at 85°C or 125°C for a duration of 96, 100, or 168 hours of test time. Burn-in is accomplished by loading the units in a fixture, usually a printed circuit board (PCB) which connects to a power supply with access to the rear wall of a standard oven. - Download [PDF]

How much charge is stored in this capacitor if a voltage of (3.00 times 10^3 V) is applied to it? Strategy. Finding the capacitance (C) is a straightforward application of Equation ref{eq2}. Once we find (C), we can find the charge stored by using Equation ref{eq1}. Solution.
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.
The amount of charge (Q) a capacitor can store depends on two major factors—the voltage applied and the capacitor''s physical characteristics, such as its size. A system composed of two identical, parallel conducting plates separated by a distance, as in Figure (PageIndex{2}), is called a parallel plate capacitor. It is easy to see the ...
