Parallel Resonance and Parallel RLC Resonant Circuit
A parallel circuit containing a resistance, R, an inductance, L and a capacitance, C will produce a parallel resonance (also called anti-resonance) circuit when the resultant current through the parallel …
Series resonant circuit, online calculator
At the capacitive reactance of the capacitor, the voltage lags the current by -90 . Therefore U L and U C are phase shifted by 180, i.e. out of phase The total resistance of the resonant circuit is called Impedance Z. Ohm''s law applies to the entire circuit. The L .
8.3: Parallel Resonance
Parallel Resonance Impedance. A parallel impedance plot is shown in Figure (PageIndex{5}). The effect is the inverse of the series case. At low frequencies the small inductive reactance results in a low impedance magnitude with a …
Q Factor: What is it? (And How Do You Measure It?)
What is Q Factor? Q factor (also known as Quality Factor or Q-factor) is defined as a dimensionless parameter that describes the underdamped condition of an oscillator or resonator.The quality factor measures the performance of a coil, a capacitor, or an inductor in terms of its losses and resonator bandwidth. ...
What are impedance/ ESR frequency characteristics …
Frequency characteristics of an ideal capacitor. In actual capacitors (Fig. 3), however, there is some resistance (ESR) from loss due to dielectric substances, electrodes or other components in addition to the capacity …
Selecting dc-link capacitors for inverters
Film capacitors are rated to much higher voltages than aluminum electrolytic capacitors and generally do not require a series connection. Aluminum electrolytic capacitors are less expensive per unit of nameplate energy, but they don''t handle as much ripple current per unit of stored energy, so the ripple current handling …
Parallel Resonance and Parallel RLC Resonant Circuit
A parallel circuit containing a resistance, R, an inductance, L and a capacitance, C will produce a parallel resonance (also called anti-resonance) circuit when the resultant current through the parallel combination is in phase with the supply voltage. At resonance there will be a large circulating current between the inductor and the capacitor due to the …
Why does a real world capacitor behave like an inductor at frequencies above its self-resonant …
The self-resonant frequency occurs at the resonant frequency of the ideal cap and series inductor (which form a tank circuit with near zero impedance at resonance). Once you go above resonance frequency, the series inductor dominates the impedance of the component, and the capacitor impedance is so low as to be negligible.
The Role of Resonant Capacitors in Power Electronics
This is referred to as self-resonance. Up to its self-resonant frequency, a capacitor acts like it''s supposed to—like a capacitor. Beyond this frequency, it starts to act like an inductor, which impedes AC current. Figure 1. Behavior of …
Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are …
The Role of Resonant Capacitors in Power Electronics
Resonant capacitors are able to store and discharge energy to achieve specific circuit behaviors that can improve power conversion efficiency, reduce losses, …

15.5 Resonance in an AC Circuit
The resonant frequency for a RLC circuit is calculated from Equation 15.17, which comes from a balance between the reactances of the capacitor and the inductor. Since the circuit is at resonance, the impedance is equal to the resistor.
15.4: RLC Series Circuits with AC
The mass and spring determine the resonant frequency. Problem-Solving Strategy: AC Circuits To analyze an ac circuit containing resistors, capacitors, and inductors, it is helpful to think of each device''s reactance and find the equivalent reactance using the rules we used for equivalent resistance in the past.
Self-resonant Frequency and High Frequency Capacitor …
Equivalent high frequency capacitor model. This means that the important characteristic distinguishing different capacitors for different frequency ranges is the capacitor''s self-resonant frequency. At this particular frequency, the capacitor will exhibit its minimum impedance and a very strong current response.

Self resonance frequency for MLCC capacitor
Is there a general self resonance frequency characteristics for MLCC capacitors? If I make a RC low pass filter, say using 1kohm and 15nF 0603 with fc = 10.6kHz, I guess it won''t work as LPF beyond the self resonance frequency of capacitor. I couldn''t find the self ...
