Description:
1.The tunable capacitor has the same function as the fixed capacitor in practical applications, but its flexibility is that it can adjust the size of the capacitor, and by changing this data, it can realize the resonance of the circuit with components such as inductors.
1.The tunable capacitor has the same function as the fixed capacitor in practical applications, but its flexibility is that it can adjust the size of the capacitor, and by changing this data, it can realize the resonance of the circuit with components such as inductors.
2.Ceramic tunable capacitors have good high-frequency characteristics and can work at hundreds of MHz or more. However, ceramic production and processing are more difficult, so the price is higher and the price of the film is lower.
3.After the ceramic adjustable capacitor is generally adjusted to the appropriate capacitance value, it does not need to be adjusted frequently. At this time, it plays the same role as the ordinary capacitor. If the debugging force is improper or the adjustment frequency is too frequent, it may be damaged Capacitor.
4.The capacitance of the ceramic adjustable capacitor: The capacitance of the adjustable capacitor is marked with the maximum capacitance and the minimum capacitance. Generally, there are 2/7P, 3/10P, 5/15P and other specifications, and the variation range is more than 3 times.
5.Any capacitor manufactured is not an ideal capacitor. There is dielectric loss. Capacitors with low dielectric loss are suitable for high-frequency circuits. The dielectric loss can only work at low frequencies. This is called the frequency characteristic of the capacitor.
6.Capacitor frequency characteristics refer to the characteristics that the capacitance and other parameters of the capacitor will change with frequency as it operates in an AC circuit (especially in a high-frequency circuit).
7.When the capacitor is operated in the high frequency circuit, the dielectric constant of the capacitor material will decrease as the operating circuit frequency increases. The electrical losses at this time will also increase. Different types of capacitors have different dielectric parameters, and they cannot substitute each other in many cases.
