AVX Corporation has developed a multilayer capacitor (MLC) chip series with new dielectric and internal electrode materials in a 0402, 0603, and 0805 size. These materials allow for a much lower equivalent series resistance than in previous versions of RF capacitors.

The UQ series have a fine-grained, high-density, high-purity dielectric material to keep out moisture, and include an electrode system that has been optimized for high-frequency performance.
