v c - voltage across the capacitor V 1 - input voltage t - elapsed time since the input voltage was applied 휏 - time constant. We''ll go into these types of circuits in more detail in a different tutorial, but at this point, it''s good to look at the equation and see how it reflects the real life behavior of a capacitor charging or discharging.
By examining this formula we can deduce that a 1F (Farad) capacitor holds 1C (Coulomb) of charge when a voltage of 1V (Volt) is applied across its two terminals. ... Although most applications do not have to take the Q factor into serious consideration, and standard capacitors may be used in those applications, Q factor is one of the most ...
When a voltage (V) is applied to the capacitor, it stores a charge (Q), as shown. We can see how its capacitance may depend on (A) and (d) by considering …
Standard Units of Capacitance. The unit of a capacitor is farads (F). One farad is a large amount of capacitance so, most of the capacitors we come across are just fractions of a farad—typically microfarads (μF), nanofarads (nF) or Picofarad (pF). ... When we increase the voltage, the capacitor charges and attains its maximum value and ...
to IEC 60384-4. For the surge voltage limits refer to "Specifications and characteristics in brief" list-ed for each series. 3.1.4 Transient voltage Some capacitor types can withstand voltage pulses exceeding the surge voltage VS. As the re-quirements differ largely depending on the individual applications, we do not state general ratings

How to choose capacitor voltage rating for ESD protection?
The capacitors are supposed to absorb the charge from injected by the ESD event. If your ESD event would still give, for example 100 V across the capacitors (and you would use 150 V capacitors because of that) then **you would be missing the point of those capacitors providing ESD protection. That 100 V would already have damaged …
The voltage rating on a capacitor is the maximum amount of voltage that a capacitor can safely be exposed to and can store. 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 ...
Recalling that in one time constant the capacitor voltage will fall to well below half of the starting value (roughly 37%), we will need a time constant several times larger than 8.3 milliseconds. ... rated for the peak voltage. The peak equivalent is 24 VAC RMS (cdot sqrt{2}) or 34 volts. Although a 35 volt rated capacitor might be tried ...
