Variable Capacitor : Construction, Types and Their Applications
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 impedance matching in antenna tuners.

6 FAQs about [Variable capacitor specifications]
What is a variable capacitor?
A variable capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically or electronically.
What is a fixed capacitor & a variable capacitor?
The capacitors with the capacitance value are fixed are known as ‘Fixed Capacitors’. Similarly, the capacitors that are with varying amounts of capacitance are known as Variable Capacitors. This type of capacitor has the capability of changing the values of its capacitance either “Electrically” or “Mechanically”.
What determines the capacitance of a variable capacitor?
The capacitance of a variable capacitor is determined by the overlapping area and distance between the rotor and stator plates. When the rotor plates are fully screwed into the fixed plates, the capacitance is at its maximum. Conversely, when the rotor plates are completely rotated out of the fixed plates, the capacitance is at its minimum.
What are the applications of variable capacitors?
There are various applications of these Variable Capacitors. Some of them are listed as follows: In this capacitor, the type called Trimmer Capacitor can be easily used on the ‘ Printed Circuit Board ‘. These are preferred in the ‘Calibration’ of the equipment. These are used in the ‘Receivers’ of radio. Where the LC circuits are present.
How do you identify a variable capacitor?
Variable capacitors are labeled with numbers or alphanumeric codes to indicate their capacitance value, rated voltage, tolerance, and temperature coefficient. Some capacitors use a 3-digit notation, where the first two digits represent the capacitance value and the third digit indicates the multiplier or the number of zeros after the second digit.
What is the range of capacitance of a capacitor?
The two plates of this capacitor can be made with metals where one plate is fixed & the other one is movable. The range of capacitance that is provided by the capacitor can range from 10 pF to 500 picofarads. The symbol of this capacitor is shown below where the arrow symbol in the image shows that is a variable one.
