This series is available with tight tolerances, meaning designers can improve matching circuits and reduce reflection loss. Capacitors under 5pF are available with tolerances as tight as +/-0.05pF; 5 to 9pF parts have tolerances down to +/-0.25pF, and tolerance is as low as +/-1% for 10 to 20pF parts.
The GQM series’ inner electrode is made of copper, which is both economical and effective when compared to palladium. The structure of the copper electrode is optimised to suppress parasitic parallel resonance, which is a key factor in realising one of the industry’s lowest ESR figures.
