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
Tantalum Capacitors: Do not resonate, thus eliminating noise issues. Ceramic Capacitors: Can generate audible noise, requiring countermeasures during final evaluation. Ⅳ Applications of Tantalum
We consider the capacitor shown in Fig. 23–4(a), which consists of two parallel circular plates
General rule of thumb with parallering caps is that you have a "large" tank capacitor (can be electrolytic or "large" MLCC) and then a smaller capacitor to catch high frequencies which can be tuned to fundamental switching frequency of the IC (think sampling frequency, PHY signaling frequency..).
Resonant capacitors are able to store and discharge energy to achieve specific circuit behaviors that can improve power conversion efficiency, reduce losses, and minimize switching stress. For advice on designing circuit
This post discusses how resonate capacitors are used to smooth waveforms, improve power factor, and reduce switching losses.
Capacitors store energy in the form of an electric field, and electrically manifest that stored energy as a potential: static voltage. Inductors store energy in the form of a magnetic field, and electrically manifest that stored energy as a kinetic motion of electrons: current.
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. An
We consider the capacitor shown in Fig. 23–4(a), which consists of two parallel circular plates connected to an external generator by a pair of wires. If we charge the capacitor with dc, there will be a positive charge on one plate and a negative charge on the other; and there will be a uniform electric field between the plates.
In resonant circuits, capacitors are key components as they resonate with coils. The resonant frequency is expressed by f=1/ (2π√LC). Therefore, changes in capacitance due to temperature variations can lead to fluctuations in the resonant frequency,

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. (Left) capacitor
The impedance of capacitors does not drop at high frequencies because they self-resonate. Passing higher-frequency AC current more easily is a fundamental property of capacitors. However, this is only true for a theoretically perfect capacitor—in practice, capacitors behave in peculiar ways at high frequencies. This is because capacitors in
High power resonant capacitors are designed to handle large voltages and currents in a small compact package size. As a result of their small size these capacitors need to be

The formula for
Capacitor failures can stem from various causes: excessive voltage or current surges, reverse polarity connections, overheating due to inadequate heat dissipation, mechanical damage from vibration or shock, environmental factors like moisture or corrosion, manufacturing defects, or simply the aging process. Proper voltage regulation, current limiting devices,

ESR and ESL can not be totally cancelled, because they are the functions of temperatures, frequencies, and currents, how-ever, they can be effectively reduced, thereby greatly

It is well known that ESL and capacitance can resonate and make a capacitor perform like an inductor at HF range; therefore it is very important to reduce the ESL of capacitors. The capacitor performance is usually evaluated by the insertion voltage gain. Fig. 2. Insertion voltage gain curves of capacitors.
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. An analogy is a mechanical pendulum, and both are a form of simple harmonic oscillator.
With the proliferation of harmonic-producing loads, the possibility of system-capacitor resonance has become a routine concern for shunt capacitor applications. Using a real-life case, this paper presents a practical procedure for assessing the likelihood and consequences of system-capacitor resonance. The results show that it is not always

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.
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 $L$.
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.
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.
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.
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.
