Currently the capacitor values shown in the table are available. Electronics
suppliers tend to stock those values that are the most popular, but larger
suppliers such as Farnell and RS tend to stock a wider range.




Farad
The capacitance is the capacity of a dielectric system to contain
electrostatic charge, defined by the ratio Q/V where Q is the electric
charge that the capacitor is capable of storing at the applied voltage V.
The unit of capacitance is the "farad", and the charge is "coulomb".




Film / Foil Capacitors
These capacitors usually have a fluid within them called an electrolyte,
which increases the charge storage capacity. The construction consists of
two aluminium plates separated by a film, which behaves as a dielectric.

The anode has an oxide layer on its surface that acts as an electrical
insulator. The second electrode is the cathode. The three layers are usually
rolled into a cylindrical shape and pins welded to the foils to make the
electrical connections.




Ideal Capacitor
Beginners usually think of capacitors as ideal components, however, there
are many factors worth considering in precision circuits. A change in
temperature will change the capacity of the dielectric system. It also
exhibits a small amount of inductance and resistance. The inductance can
affect high frequency operation whilst the resistance can dissipate energy
in the form of heat. Capacitors wear out fast under electrical stress, and
excessive heat causes their values to drift.




History
The word "capacitor" is a modern term, because in 1782 Voltaire named it condenser. The
idea of the condenser dates back to the invention of the Leyden jar in 1745.
It was simply a glass jar filled with water and a nail at the centre for an
electrode.
