6 FAQs about [High frequency air adjustable capacitors]

Are air variable capacitors polarized?

Air variable capacitors are used to tune L-C resonant circuits found in radio frequency power amplifiers. They are also found in antenna impedance matching networks. Their simple design offers high voltage ratings, low leakage and a high quality factor (Q). Air variable capacitors are non-polarized.

What are the simplest air capacitors?

The simplest air capacitors are made of two conductive plates separated by an air gap. Air capacitors can be made in a variable or fixed capacitance form. Fixed capacitance air capacitors are rarely used since there are many other types with superior characteristics. Variable air capacitors are used more often because of their simple construction.

What are air variable capacitors?

Air variable capacitors are also called variable capacitors, adjustable capacitors and tuning capacitors. The plates form half circles with one set of stationary plates and another set that rotates on an attached shaft. Maximum capacitance is achieved when the plates are fully meshed.

What are air capacitors used for?

They are used in radio tuning applications, antenna tuning and so on. Air capacitors are interesting for military applications due to their inherent resistance to electromagnetic pulses which can be created intentionally to destroy electronic equipment, but are also a byproduct of a nuclear explosion.

Why are air capacitors unsuitable for high voltages?

The dielectric strength of air is inferior to many other materials, which makes air capacitors unsuitable for high voltages. Air capacitors have a small capacitance which usually lies between 100pF and 1nF. The maximum working voltage depends on the physical dimensions of the capacitor.

What is a variable capacitor used for?

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 impedance matching in antenna tuners.
