Tunable filters have been mostly designed with an electrical control. The controlling components are typically variable capacitors. This is due to the fact that variable inductors are still considered something exotic. However, tunability of the lumped-element filters with the only variable capacitors as controlling components is limited. On the other hand, …

The diaphragm''s secondary function as one plate of two capacitors provides a convenient method for measuring displacement. Since capacitance between conductors is inversely proportional to the distance separating them, capacitance on the low-pressure side will increase while capacitance on the high-pressure side will decrease:
Lessons up front, justification later: Build or buy your capacitor FIRST, and then finish the rest of your loop design based on that capacitor Use a vacuum variable capacitor. From what I have experienced, many starting points with mag-loops nearly all end with the purchase of a vacuum variable cap. Save yourself time and…
Sealed variable capacitance makes it simple to produce static induction during prolonged use of the film medium; adjustments are made in response to "Kaka" noise and general alcohol cleaning. But because alcohol is so volatile, it will collect static electrons on the …
A Variable Capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically or electronically. Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio (therefore it is sometimes called a tuning capacitor or tuning condenser), or as a variable reactance, e.g. for ...
A vacuum variable capacitor. A vacuum variable capacitor is a variable capacitor which uses a high vacuum as the dielectric instead of air or other insulating material. This allows for a higher voltage rating than an air dielectric [1] using a smaller total volume. However, many dielectrics have higher breakdown field strengths than vacuum: 60-170 MV/m for …

The common types of variable capacitors are the following: 1) Air Variable (Air-Gap Trimmer) – These variable capacitors have a rotatable set of plates called a rotor, and a fixed set of plates called a stator. The capacitance is varied by rotating a control shaft which varies the distance or surface area between the plates.
For example, the multilayer ceramic capacitor GRM188R71E104KA01D is a fixed capacitor from Murata Manufacturing and has a fixed capacitance of 100nf (or sometimes referred to as 0.1uf) and a fixed voltage of 25 volts. Variable Capacitors: A variable capacitor can be mechanically adjusted to change the amount of energy it can …
( 1 ) Single variable capacitor. The single variable capacitor is composed of a set of movable plates, a set of fixed pieces and a rotating shaft. Single variable capacitor film is used as a medium, and the moving sheet and the stator are sealed with a plastic shell, so the sealed single variable capacitor is called a variable …

The applications of the variable capacitor include the following. Trimmer capacitors are used where a capacitance value is needed to be matched to a particular circuit in the manufacturing process. The main reason to use this capacitor is, the components used in the circuit have own tolerances. So the tolerance values can be changed by 20%

These magloops also have a very narrow bandwidth, requiring a variable capacitor for tuning to the operating frequency. As voltages on the order of thousands of volts develop across the capacitor, air variables or vacuum variable capacitors are used. To maintain the lowest series circuit resistance, the connections are preferably soldered and a ...
