The property exhibited by two conductors separated by a dielectric whereby an electric charge becomes stored between the conductors. Capacitance is measured in "farads" and is identified by the letter "C".
CAPACITOR
A passive electronic circuit component consisting in its simplest form, of two metal electronics separated by a dielectric.
CRYSTAL EQUIVALENT CIRCUITS
A crystal device consists of a quartz resonator with metal plating. This plating, as shown below, is located on both sides of the crystal and is connected to insulated lead on the crystal package. The device exhibits a piezoelectric response between the two crystal electrodes as expressed in the equivalent circuit shown below:
CRYSTAL IMPEDANCE (C.I)
Used in place of the word "resistance".
CRYSTAL IMPEDANCE METER (C.I.M)
See test set.
COLD WELD
Procedure in which the base and can are dissimilar metals that are pressed together to form one metal.
CONTOUR
A modification to one or both of the major faces of a resonator plate in which the face is altered to have a complete spherical configuration. See "Bevel"
COUPLED MODE
An unwanted mode that becomes energized at the same frequency as the desired mode, thereby draining energy from the desired mode.
COVER
The upper portion of a crystal holder. See "Can" & "Holder".
CRYSTAL
A genetic term used in place of the more complete expression "piezoelectric quartz unit".
