About Us

Quantic Evans, a wholly owned subsidiary of Quantic™ Electronics since 2020, is an AS9100/ISO 9001 certified developer and manufacturer of high-reliability, power dense capacitors. Its products provide superior size, weight, power and reliability specifications, enabling customers to develop next-generation electronic systems for aerospace, defense and industrial applications.

Quantic Evans, formerly known as Evans Capacitor Company, was founded in 1996 by its President Dave Evans and CEO Charlie Dewey. After extensive research and experimentation, Dave Evans discovered that combining the two capacitor technologies tantalum and ruthenium oxide yielded the most power dense capacitor in the industry. These hybrid capacitors, known as EVANSCAPS, provide significant savings of space and weight compared to other capacitor technologies, in a high reliability ruggedized package providing MTBF > 5 million hours.

EVANSCAPS are specified for mission-critical aerospace, defense, and energy exploration applications including radar, laser, power hold-up/bridge power, downhole drilling, electronic warfare and more. EVANSCAPS replace standard military capacitors, and/or augment batteries and power supplies where size, weight, reliability and quality are critical factors in component selection.

Quantic Evans' production facilities, located in East Providence RI, and Sanford ME, USA follow the most stringent guidelines for quality and performance. All Quantic Evans products undergo extensive testing and evaluation.

EVANSCAPS are qualified and in service with all tier 1 aerospace and defense contractors. Quantic Evans welcomes the opportunity to work directly with engineers and product designers to help solve their application challenges and achieve their goals to develop next-generation electronic systems for aerospace, defense and industrial applications.
