What happens when an inductor is operated above its self-resonant frequency?

A physical inductor is not a perfect component; the parallel wires of its coil naturally create small amounts of stray, or parasitic, capacitance. Because of this, every inductor acts like a parallel LC circuit consisting of its intended inductance and its unintended capacitance. At a certain frequency known as the self-resonant frequency, the inductive reactance and the capacitive reactance cancel each other out. As the frequency increases above this self-resonant point, the capacitive reactance drops and becomes the dominant force, meaning the component begins to act more like a capacitor than an inductor.
