Abstract
A variable electronic component in the nature of a trimmer capacitor has greatly increased voltage rating and capacitance range, while eliminating possible failure modes. An annular opening formed in a stationary electrode is surrounded by plastic dielectric material so as to receive in interference fit a circular sleeve of an opposing impedance varying electrode. By filling the air gap with plastic dielectric material, no air contributes to the effective dielectric, while at the same time, preventing shorting as a result of loose metallic particles which might be present.
