6 FAQs about [Capacitor Requirement]

What is the maximum voltage a capacitor can handle?

It will also depend on the physical size requirement. The capacitor physical size is directly proportional to the voltage rating in most cases. For instance, in the sample circuit above, the maximum level of the voltage across the capacitor is the peak level of the 120Vrms that is around 170V (1.41 X 120V).

How to select capacitors?

Aside from the capacitance, another thing to consider on how to select capacitors is the tolerance. If your application is very critical, then consider a very small tolerance. Capacitors come with several tolerance options like 5%, 10% and 20%. It is your call which is which.

Is there a limit to the speed of a capacitor?

There is a limit to how quickly the voltage across the capacitor can change. An instantaneous change means that dv/dt d v / d t is infinite, and thus, the current driving the capacitor would also have to be infinite (an impossibility). This is not an issue with resistors, which obey Ohm's law, but it is a limitation of capacitors.

What is a basic capacitor?

W W is the energy in joules, C C is the capacitance in farads, V V is the voltage in volts. The basic capacitor consists of two conducting plates separated by an insulator, or dielectric. This material can be air or made from a variety of different materials such as plastics and ceramics.

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%.
