Vacuum variable capacitor
A vacuum variable capacitor. A vacuum variable capacitor is a variable capacitor which uses a high vacuum as the dielectric instead of air or other insulating material. This allows for a higher voltage rating than an air dielectric [1] using a smaller total volume. However, many dielectrics have higher breakdown field strengths than vacuum: 60-170 MV/m for teflon, 470-670 MV/m for …

Why does a real world capacitor behave like an inductor at …
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.
