Contact Evans

Evans (formerly Quantic Evans) hybrid wet tantalum capacitors are the most power dense in the industry, providing significant SWaP savings when compared to traditional capacitor technologies. Our trusted products are qualified and in service with all tier 1 aerospace and defense contractors.

Our industry-leading power density is the result of our patented proprietary hybrid wet tantalum technology, which combines a traditional Tantalum Pentoxide anode with a Ruthenium Oxide cathode to create capacitors that excel in the most demanding defense, aerospace, and energy applications.

Backed by a highly experienced technical team, Evans partners with customers to identify the best solution for each application. We also offer complete custom solutions, enabling customers to streamline their processes and meet unique electrical, mechanical, and environmental requirements.
