Capacitors are divided into two mechanical groups: Fixed-capacitance devices with a constant capacitance and variable capacitors. Variable capacitors are made as trimmers, that are typically adjusted only during circuit calibration, and as a device tunable during operation of the electronic instrument. The most common group is the fixed capacitors.
1. The capacitor that can be adjusted is called a variable capacitor. The variable capacitor can be divided into air medium and organic film medium according to different media. According to the different structure, it can be divided into single variable capacitor ,double variable capacitor and quadruple variable capacitor.
( 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 capacitor.
( 2 ) Double variable capacitor dual variable capacitor consists of two sets of moving pieces, two sets of fixed pieces and a rotating shaft. As the motion piece of the dual variable capacitor is installed on the axis of the same root, the two groups of capacitance can be adjusted at the same time when the rotating shaft is rotating.
As the motion piece of the dual variable capacitor is installed on the axis of the same root, the two groups of capacitance can be adjusted at the same time when the rotating shaft is rotating. (3) the quadruple variable capacitor quadruple variable capacitor consists of four sets of variable capacitors, which consist of four variable capacitors.
Capacitors are characterized by their capacitance, which measures the amount of electrical charge that can be stored on the plates of the capacitor for a given voltage. The unit of capacitance is the farad (F), but in practice, capacitors are typically measured in smaller units such as microfarads (μF) or picofarads (pF).
