Part 4: The Capacitor is the Hidden Star of

The two basic properties of a capacitor are that it can store electric charges and that it passes higher-frequency AC currents more easily. However, in high-frequency ranges, the capacitor begins to reveal a different side. This is because the subtle inductive component within the capacitor becomes more dominant, and the capacitor alone begins to behave like a resonant

Capacitor Self-resonant Frequency and Signal Integrity

The real behavior of a capacitor and inductor can cause the LC oscillator''s actual resonance frequency to deviate from the ideal designed value. There may even be multiple resonance or antiresonance peaks in the network''s impedance spectrum. This also affects the bandwidth of the matching network. Self-resonance of two different capacitors.

6 FAQs about [Capacitors that can resonate]

Why is a capacitor a resonant circuit?

This is because the subtle inductive component within the capacitor becomes more dominant, and the capacitor alone begins to behave like a resonant circuit. Resonant circuits, which combine a capacitor and an inductor (coil), are indispensable for tuning in communication and broadcasting equipment.

How to raise the resonant frequency of a capacitor?

Suppose we start by considering the resonant circuit of a capacitor in parallel with an inductance, as shown in Fig. 23–16 (a). This circuit will resonate at the frequency $\omega_0=1/\sqrt {LC}$. If we want to raise the resonant frequency of this circuit, we can do so by lowering the inductance $L$.

What causes resonance in a circuit involving capacitors and inductors?

Resonance of a circuit involving capacitors and inductors occurs because the collapsing magnetic field of the inductor generates an electric current in its windings that charges the capacitor, and then the discharging capacitor provides an electric current that builds the magnetic field in the inductor. This process is repeated continually.

What type of capacitor is best for resonant capacitors?

For resonant capacitors, we typically recommend multilayer ceramic capacitors (MLCCs) with very stable capacitance, tight tolerances, and low dissipation to prevent overheating, such as our 500V-1kV 4.7nF-39nF C0G capacitors.

What are the properties of a capacitor?

It may contain outdated technical information and references to products not currently available from TDK. The two basic properties of a capacitor are that it can store electric charges and that it passes higher-frequency AC currents more easily. However, in high-frequency ranges, the capacitor begins to reveal a different side.

Can a resonant circuit use a coil and a parallel-plate capacitor?

For instance, if we want a resonant circuit at high frequencies we will not try to design one using a coil and a parallel-plate capacitor. We have already mentioned that the parallel-plate capacitor we have been analyzing has some of the aspects of both a capacitor and an inductance.
