Hi-Rel Capacitors for Mission-Critical Environments.
Evans Group unites four industry leaders—Evans, Paktron, UTC, and Eulex—to deliver one of the industry’s most specialized and comprehensive portfolios of power-dense, high-reliability capacitors engineered for mission-critical environments across defense, aerospace, energy, and advanced RF systems.
Evans | Hybrid Wet Tantalum
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.

Paktron | Multilayer Polymer Film
For over 60 years, Paktron (formerly Quantic Paktron) has been recognized for capacitor innovation and its proprietary stacked, multilayer polymer (MLP) construction. This advanced design delivers superior mechanical and electrical performance compared to traditional wound film capacitors, and serves as a self-healing alternative to ceramic capacitors with strong high-ripple-current handling—making Paktron a trusted choice for a wide range of demanding applications.
AEC-Q200 qualified options available.
- Wide Bandgap Applications
- VPX Systems
- Voltage smoothing
- Timing/tuning
- Switched mode power supplies
- Low energy pulse applications (ignition, systems, etc.)
- L-C filtering (power converters, power amplifiers, etc.)

Eulex | High Frequency Ceramic
Eulex (formerly Quantic Eulex) pioneered an embedded-electrode RF capacitor architecture that delivers an order-of-magnitude increase in capacitance density with ultra-low parasitics. The result is broadband, ultra-low-loss, high-power performance across decades of frequency—ideal for DC blocking, decoupling, and impedance matching. The technology is compatible with standard surface-mount assembly processes, improving reliability, simplifying manufacturing, and reducing (or eliminating) tuning.
