The inductor also has its own resonance frequency. This is why some high frequency inductors have their windings far apart - to reduce the capacitance. Perfect, thankyou. So at some frequency where omega L = 1 / {omega c}, the inductor will resonate with itself (the ideal inductor with the parasitic capacitance). thanks for the input.
As the frequency increases, the impedance of the inductor increases while the impedance of the parasitic capacitor decreases, so at some high frequency the impedance of the capacitor is much lower than the impedance of the inductor, which means that your inductor behaves like a capacitor. The inductor also has its own resonance frequency.
While pouring over texts with explanations of various aspects is one approach to overcoming this hurdle, such texts rarely include an explanation of the high-frequency characteristics of inductors and capacitors, which are basic electric circuit elements.
・When the capacitance and the ESL are smaller, the resonance frequency is higher, and the impedance in the high-frequency region is lower. ・The larger the capacitance, the lower is the impedance in the capacitive region. ・The smaller the ESR, the lower is the impedance at the resonance frequency.
Why does a real world capacitor behave like an inductor at frequencies above its self-resonant frequency? I've come across some graphs comparing the impedance of a capacitor over frequency and it understandably declines as frequency increases -- up until a certain point. Afterwhich, the impedance begins to increase, like an inductor.
In the capacitive characteristic region, the larger the capacitance, the lower is the impedance. Moreover, the smaller the capacitance, the higher is the resonance frequency, and the lower is the impedance in the inductive characteristic region. Our explanation of the frequency characteristics of capacitor impedance may be summarized as follows.
