Variable capacitors are capacitors with a capacitance that can be varied based on the requirement to a specific range of values. Variable capacitors consist of plates made of metal. ... it is necessary to ensure that the impedance of the capacitor is sufficiently low. The capacitor rated voltage must be greater than the peak voltage …
Understanding voltage rating of a capacitor
The DC working voltage is the maximum DC voltage and NOT the maximum AC voltage. A capacitor with a DC voltage rating of 100 volts DC cannot be safely used to an AC voltage of 100 volts. This is because an alternating voltage that has an RMS value of 100 volts will have a peak value over 141 volts (√2 x 100).

Capacitor Specifications: what they mean
Some aspects that limit the working range of a capacitor are the voltage - this falls with increasing temperature; the ripple current - again lower with increasing temperature. The lower temperature specification can be governed by a number of factors. One is the electrolyte operation in components such as electrolytic capacitors.
Capacitor Characteristics
If you need a capacitor in the range of 1µF-1mF, you''re most likely to find it in an electrolytic form. They''re especially well suited to high-voltage applications because of their …

OverviewNon-ideal behaviorHistoryTheory of operationCapacitor typesCapacitor markingsApplicationsHazards and safety
In practice, capacitors deviate from the ideal capacitor equation in several aspects. Some of these, such as leakage current and parasitic effects are linear, or can be analyzed as nearly linear, and can be accounted for by adding virtual components to form an equivalent circuit. The usual methods of network analysis can then be applied. In other cases, such as with breakdown voltage, the effec…
