Hi-Reliability Capacitors for Fuze and Munitions

Engineered for Mission-Critical Energy Delivery

When failure is not an option, power delivery systems must perform flawlessly—under extreme shock, temperature, and time constraints. Evans Group brings together Evans, Paktron, and UTC to deliver a complete capacitor solution for fuze, detonation, and munitions systems.

Backed by decades of deployment across programs like PAC-2 (GEM-T), PAC-3, Tomahawk, and many other classified programs, our technologies are trusted in the most demanding defense environments.

The Challenge: Reliable Energy, Instantly Delivered

Modern munitions systems demand:

  • Precise, high-power pulse delivery
  • Stability across extreme environments (-55°C to 200°C+)
  • Compact, SWaP-constrained designs
  • Long-term storage reliability with instant readiness

Traditional components often fall short under:

  • High shock and vibration
  • Rapid discharge requirements
  • Elevated temperature conditions

The Solution: Integrated Capacitor Technologies
