The MAXIMUM value of capacitance is normally what is specified for variable capacitors. Many makers also specify a minimum value range, which is less predictable. But in all cases the minimum value is not zero. In many cases the minimum is between 5% and 10% or the maximum. Is the question asking for a number? Or an explanation of the concept?
The nominal value of the Capacitance, C of a capacitor is the most important of all capacitor characteristics. This value measured in pico-Farads (pF), nano-Farads (nF) or micro-Farads (μF) and is marked onto the body of the capacitor as numbers, letters or coloured bands.
The capacitance of a capacitor can change value with the circuit frequency (Hz) y with the ambient temperature. Smaller ceramic capacitors can have a nominal value as low as one pico-Farad, ( 1pF ) while larger electrolytic’s can have a nominal capacitance value of up to one Farad, ( 1F ).
Like 0.47 µF or 22 pF. It is a bit confusing, but it’s easy to learn what it means. In this article you will learn the most standard capacitor values, the prefixes used and how to calculate a capacitor value for your circuit. Capacitor values are given in Farad. The symbol used is F. It’s named after the English physicist Michael Faraday.
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%.
This little one is 2 to 15pF. (black one) The green one is about the same. Depends on the capacitors design. Anywhere from 1% to 20% of the maximum capacitance. Check the data sheet. A tunable (rotating) capacitor consists of plates that are spaced apart by some measure. The spacing is what derives a given capacitance.
