Very often, multiple stator/rotor sections are arranged behind one another on the same axis, allowing for several tuned circuits to be adjusted using the same control, e.g. a preselector, an input filter and the corresponding oscillator in a receiver circuit. The sections can have identical or different nominal capacitances, e.g. 2 × 330 pF for AM filter and oscillator, plus 3 × 45 pF for tw. When a capacitor is charging or discharging, the amount of charge on the capacitor changes exponentially. [pdf]
Whether it is a simple LC circuit or a complex circuit used in advanced communication systems, the principles of capacitance and inductance remain at the core. Variable capacitors, a key component in these circuits, provide the much-needed ability to adjust resonant frequencies, adding versatility to these circuits.
Variable capacitors consist of a set of fixed plates and a set of movable plates. By changing the position of the movable plates relative to the fixed plates, we can adjust the capacitance and thus the resonant frequency of the tuning circuit.
Usually two variable capacitors are adjusted by a single control spindle. The arrow symbol indicates a variable capacitor (adjustable by the equipment user, and the T shaped diagonal indicates a preset capacitor, for technician adjustment only. The dotted line connecting a pair of variable capacitors indicates that they are ganged.
Altering the physical parameters that dictate capacitance, such as the conductor plates' surface area (A), spacing between them (d), and permittivity (ε) of the dielectric material between them, can produce this shift in capacitance. The adjustment of the distance (d) between the plates is another feature of certain variable capacitors.
Adjustable capacitance makes these capacitors essential for fine-tuning electronic circuits. In electronic applications like radios and oscillators, their ability to adjust capacitance by changing surface area, plate spacing, or dielectric material allows for precise control.
In electronic applications like radios and oscillators, their ability to adjust capacitance by changing surface area, plate spacing, or dielectric material allows for precise control. Anyone interested in electronics must understand these components' operation and maintenance, whether they are electronically or mechanically adjusted.

A feedthrough is a used to carry a signal through an enclosure or printed . Like any conductor, it has a small amount of . A "feedthrough capacitor" has a guaranteed minimum value of shunt capacitance built in it and is used for bypass purposes in ultra-high-frequency applications. Feedthroughs can be divided into power and instrumentation categories. Pow. A feedthrough capacitor is a ceramic tube coated with a metal layer, forming two “plates” with one in the inside and the other on the outside. [pdf]
Ceramic feedthrough capacitor with cable lug and a capacitance of 1 nF. A feedthrough is a conductor used to carry a signal through an enclosure or printed circuit board. Like any conductor, it has a small amount of capacitance.
This falls under the category of electromagnetic control (EMC). Some feedthrough capacitors are used in assemblies that also include inductors. This permits the use of the various filter arrangements such C-type filters, LC-type filters, Pi-type filters and T-type filters (see below image). Feedthrough capacitor filters. (Image: Author.)
In contrast, a feedthrough capacitor provides superior high-frequency filtering. The feedthrough capacitor has a very small parasitic inductance, a very low bypass impedance, and (because of its isolation mounting) it eliminates coupling between its input and output. For simple, noncritical filtering, discrete filter circuitry can be used.
RF feedthrough capacitors are mostly used for high power applications such as dielectric and induction heating equipment, plasma generators, and radio broadcast transmitters. They are also widely used for matching high power tuned circuits, bypassing and coupling RF circuits, and coupling antenna circuits.
The inductance of these components is in the series branch. Feedthrough capacitors are commonly used in today’s AC/DC supply lines to suppress harmful interference. They are also widely used in electronic circuits for base stations, telephone exchanges, shielded rooms, power supplies, and so on.
Signals, data lines, and AC power lines, telecommunications equipment, microwave filters, industrial computers, and composite circuit filter components are all examples of where feedthrough capacitors and other filters are employed.
