Variable amperage capacitor is a capacitor whose electric capacity can be continuously adjusted within a certain range, and it is a kind of commonly used adjustable electronic components, including single-link variable capacitor, double-link variable capacitor, multi-link variable capacitor and trimmer capacitor, etc.
1. The word symbol is “C”.
2. The main parameter is the maximum capacitance.
3. The characteristics are that the ampacity can be changed, and it can be divided into linear capacitor type, linear frequency type, logarithmic type, etc.
4. The main function is to change and adjust the resonant frequency of the circuit.
5. Capacitor whose capacitance can be continuously adjusted within a certain range is a common adjustable electronic component.
