The different ceramic materials used for ceramic capacitors, paraelectric or ferroelectric ceramics, influences the electrical characteristics of the capacitors. Using mixtures of paraelectric substances based on titanium dioxide results in very stable and linear behavior of the capacitance value within a specified temperature range and low losses at high frequencies.
Eitel/McCullough and other manufacturers of high power RF tubes use the following code since 1945: [2] An initial digit denoting the number of electrodes: 2 – Diode; 3 – Triode; 4 – Tetrode; 5 – Pentode; Up to 2 letters denoting the construction type and the cooling method: R or a dash ("-") – Glass envelope, radiation cooling; C ...
The rated capacitance C R or nominal capacitance C N is the value for which the capacitor has been designed. Actual capacitance depends on the measured frequency and ambient temperature. Actual capacitance depends on the measured frequency and ambient temperature.
For example, in charging such a capacitor the differential increase in voltage with charge is governed by: = where the voltage dependence of capacitance, C(V), suggests that the capacitance is a function of the electric field strength, which in a large area parallel plate device is given by ε = V/d.
The capacitance value specified in manufacturers' data sheets is called the rated capacitance C R or nominal capacitance C N and is the value for which the capacitor has been designed. Standardized measuring conditions for electrolytic capacitors are an AC measurement with 0.5 V [ clarification needed ] at a frequency of 100/120 Hz and a ...

Vacuum variable capacitors are commonly used in high-voltage applications: 5000 volts (5 kV) and above. They are used in equipment such as high-powered broadcast transmitters, amateur radio RF amplifiers and large antenna tuners. Industrially they are used in plasma generating equipment, for dielectric heating, and in semiconductor ...
