Is it possible to combine several capacitors into one capacitance (switch them on in parallel)?

Question

Electronics

The actual capacitance of capacitors differs from the marking. And if, for example, we need a 10 microfarad capacitor, then it is worth combining 2 5 microfarad capacitors, because their capacitance will be different, and they will operate at different frequencies. This is true? Or in what cases it is possible to unite, and in some cases it is impossible?

Answer 1

In parallel, you can combine as many capacitors as you like, the capacitances are summed up.
At different frequencies, they will work as separately.
Tell me better in plain text what do you need??

Answer 2

Can. It is important that the voltage does not exceed the maximum for each of the capacitors.
You can also, on the contrary, connect them in series to increase the voltage limit

Answer 3

Take containers of the same type and connect them in parallel. The capacitance is summed up, the allowable voltage is the smaller of the allowable voltage of the individual capacitances.
If, of course, for example, you want to connect ceramics and electrolyte at high frequencies in parallel, then there may be nuances of use. But then you already need to look at what actual goal you are trying to achieve

Answer 4

where looking.
in tying a processor with a frequency of 3.4 GHz - it's not worth it, but it's not necessary either. especially capacious conders have nothing to do there, and low-capacity, yes SMD-shki, will cost less as a whole.
but capacious large ones, like in a power supply filter, will cost less separately.
after all, giants (high voltage and capacitance) are always less massive than typical ones. and the range of manufacturers for the giants is less.
and this is absolutely normal, tk. special accuracy is not required of them, there is no HF there, the only negative is the dimensions.
