Capacity of the Capacitor and attachments Mili Micro Pico Nano — It turns out everything is simple

Mili Micro Pico Nano consoles and confusion with Capacity

The capacitor is its capacity, as well as some of the confusion that arises among beginning radio amateurs associated with this.

Often when I touch on a capacitor in my videos or articles. Sometimes I hear questions: What is the difference between microfarad, nanofarad, picofarad, and so on. Even beginner electronic engineers sometimes get confused with these names.

I understand that for many this seems elementary and not even worth discussing.

But remember yourself when you were just starting out. I think you also had a lot that was unclear and you wanted to know.

Therefore, I think this needs to be dealt with once and for all.

What do these prefixes mean?

Prefixes that are used to designate the capacitance of a capacitor such as mili, micro, nano, pico, what do they mean?

Let’s use a little bet from Wikipedia :

SI prefixes  ( decimal prefixes ) are prefixes before the names or designations of units of measurement of physical quantities, used to form multiples and submultiples that differ from the base unit by a certain integer number of times, which is a power of 10. Decimal prefixes are used to reduce the number of zeros in numerical values physical quantities.

The concept of a prefix in your own words

Well, now let’s try to explain more clearly and exactly how this is related to the capacitance of the capacitor.

Since the unit of measurement of the capacitor is taken to be a rather large Farad. I think most radio amateurs in their practice have never encountered capacitors of such capacity.

These attachments are used to reduce capacity.

If we take and divide our Farad by 1.000 then we get miles of Farads. This is also a capacity that is not often found in the practice of radio amateurs.

But if we take it and divide it by a million (1,000,000), then this will already be a microfarad. In our practice, microfarads are found more often, or one might even say very often, and as a rule these are electrolytic capacitors.

If we divide this by a billion, this is already nine zeros, then our capacity here will already be in nanofarads. Capacitors with such capacities are also quite popular.

And now if we divide by a trillion — this is already one followed by 12 zeros, then here we get the peak capacity in farads. Most often, such containers are used by radio amateurs who work on radio receivers and radio transmitters. Although these capacities are also used in other areas of electronics.

Table for better understanding

Here each value is represented in micro nano and pica farads:
