Fundamental Knowledge of High-Frequency Characteristics of Inductors and Capacitors—Impedance and Resonance 3

fr = 1 / (2π√LC)

Among them, fr is the resonant frequency, L is the inductance, and C is the capacitance.  diode

For capacitors, the formula for calculating the resonant frequency is:

fr = 1 / (2π√LC)

The resonant frequency is related to the values of inductance and capacitance. When the frequency is equal to the resonant frequency, the impedance of the inductor or capacitor reaches its minimum value. In high-frequency circuits, resonance can be used to screen signals of specific frequencies or achieve frequency selection.diode

In summary, inductors and capacitors have different impedance and resonant characteristics in high-frequency circuits. Understanding their characteristics can help us better design and analyze high-frequency circuits.
