Tuning capacitors come in several types, each with its own characteristics and applications: Variable Capacitors: These capacitors have adjustable capacitance achieved by changing the distance between their plates or altering the effective plate area. They are commonly used in tuning radio frequency circuits and oscillators.

What is a tuning capacitor?

Tuning capacitors take a host of forms. Some are adjusted by means of screwdrivers or tuning tools. These are generally called trimmers or padders. They are set for resonance just once, then left in that posi- tion. Trimmer capacitors may be made with metal plates; insulation between the plates can be made of ceramic, plastic, mica or glass.

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.
