Evans Capacitor – High Energy Density Caps

“Hermetically sealed Evans Hybrid Capacitor and Capattery devices have numerous patented features that provide demonstrated advantages over standard capacitor technologies.”

Evans Capacitor – High Energy Density Caps

“Evans maintains the highest levels of quality, and is fully compliant with ISO 9001 and AS9001 standards.” The unique chemistry and construction  provide 5 to 10 times the volumetric energy  density of aluminum electrolytic capacitors.

Technical Papers of Evans Capacitor

The Littlest Big Capacitor – An Evans Hybrid – Presented at the Fifth International Seminar on Double Layer Capacitors and Similar Energy Storage Devices, December 4-6, 1995

Capattery – SuperCapacitor – Designed for longer duration power hold-up and memory back-up applications.  Full operating temperature range of -55C to 85C

High energy density, up to 3 joules per cc, High reliability, 25 yrs., >1,000,000 cycles

Hybrid capacitors provide very high power and energy from devices much smaller and lighter than electrically equivalent tantalum wet, tantalum chip, or aluminum electrolytic capacitors.

Typical applications replace standard military capacitors, or augment batteries and power supplies where size, weight, reliability and quality are important factors of component selection.
