The Evans Group

Evans is the pioneer in high-reliability, power-dense capacitors for demanding environments and pulsed-power applications.

1996 | EVANSCAPS
Founded in 1996 by President Dave Evans and CEO Charlie Dewey in East Providence, RI, Evans Capacitor Company pioneered a hybrid capacitor technology that combines tantalum and ruthenium oxide to deliver exceptional power density. Marketed as EVANSCAPS, these ruggedized, high-reliability capacitors provide significant space and weight savings versus standard military capacitor technologies, with MTBF > 5 million hours.

1996–2020 EVANSCAPS are specified for mission-critical aerospace, defense, and energy exploration applications—including radar, laser, power hold-up/bridge power, downhole drilling, and electronic warfare—where size, weight, reliability, and quality are decisive.

• Manufactured in the United States in East Providence, Rhode Island, with a satellite facility in Sanford, Maine, products are built under stringent quality guidelines and undergo extensive testing and evaluation.
• EVANSCAPS are qualified and in service with Tier 1 aerospace and defense contractors, supported by a long-standing culture of direct collaboration with engineers and product designers to solve demanding application challenges.

2020 - Arcline Investment Management acquired Evans Capacitor Company. Post-acquisition, Evans went to market as Quantic Evans. Evans continued to serve mission-critical programs with deep application expertise and long-standing customer relationships.

2022 -Arcline Investment Management acquired Tantalum Pellet Company (TPC), located in Phoenix, AZ. As part of a vertical integration strategy, TPC became a second satellite location supporting Quantic Evans.

January 1, 2026
Evans Group launches, unifying Evans, Paktron, UTC, and Eulex under a single customer-facing umbrella to make it easier to explore and compare complementary capacitor technologies across the portfolio. 

Paktron brings multilayer polymer film capacitor expertise and a long U.S. manufacturing legacy.

Paktron’s roots trace back to the earliest days of modern electronics manufacturing. From pioneering automated assembly concepts in the 1950s to advancing multilayer polymer film capacitor technology, Paktron has consistently evolved to meet the demands of high-reliability, high-performance applications.

Early 1950s–1954 | Foundations in electronics manufacturing innovation

• Early 1950s — A team at the National Bureau of Standards begins mechanizing electronic-assembly construction, laying the groundwork for a new era of electronics manufacturing.

• 1953 — The NBS development known as “Project Tinkertoy” is completed and released publicly, accelerating industry interest in modularized and automated electronic assembly.

• Early 1954 — Companies including ACF Industries recruit the NBS engineers and establish ACF Electronics in Alexandria, Virginia, to commercialize the technology.

1954–1959 | Building capability and discovering the opportunity in film capacitors

• 1954–1959 — ACF Electronics develops products and machines for the fast-growing television industry, manufacturing components ranging from tube sockets and ceramic parts to film capacitors—the product category that becomes its long-term focus.

• Late 1950s — As market pressures increase for complex modules, film capacitors emerge as the stronger product path, alongside experimentation with a new “self-coating” design.

1960–1962 | Paktron is formed and launches a flagship capacitor line

• 1960 — Illinois Tool Works (ITW) purchases ACF Electronics and renames the business Paktron, quickly pivoting away from complex modules and toward film capacitor production.

• 1962 — Paktron introduces the Filmatic® capacitor, featuring self-coating polyester film—an innovation that scales into a major volume driver over the next decade.

1966–1970 | Lynchburg becomes the manufacturing heart

• August 1966 — Paktron begins Lynchburg operations in a rented facility at 6th & Church Streets to produce Filmatic capacitors—an early investment in Lynchburg as a manufacturing base.

• November 1969 — Paktron purchases land, builds the present Lynchburg plant, and occupies it—establishing long-term production scale.

• May 14, 1970 — Official Opening: Paktron–Lynchburg, including open house/plant tours and hosted events, formally marks the site’s significance.

• 1970 — Paktron introduces Micromatic®, an axial-leaded, self-cased capacitor, broadening the film capacitor portfolio beyond Filmatic.

1970s | Growth, broader form factors, and adapting to market shifts

• Early–mid 1970s — Paktron expands its range of constructions and form factors, including advances in metallized designs and termination methods, as the Filmatic line becomes a high-volume product.

1980–early 1980s | A technology pivot: ultra-thin film and Interleaf®

• 1980 — ITW identifies ultra-thin metallized film as the foundation for a new growth wave in capacitors and invests heavily in new manufacturing technology.

• Early 1980s — Paktron launches the Interleaf® Technology project to enable thinner films, higher-temperature films, and access to larger markets—returning the business to a strong growth trajectory.

• Early 1980s (process milestone) — Interleaf is documented as a stacked-film approach: film is segmented and aligned into stacks (“ropes”), margins are laser-formed, aluminum termination is deposited, and the structure is reformed under heat and pressure (patent referenced).

1982 | Consolidation and focus in Lynchburg

• 1982 — Paktron consolidates manufacturing by vacating and selling the Vienna, Virginia plant and moving active product lines to Lynchburg, concentrating capability and scale.

1985–1996 | New product families come online (Interleaf era)

• 1985 — Production start-up of Angstor® capacitors.

• 1992 — Production start-up of Capstick® capacitors.

• 1996 — Production start-up of SurfFilm® NG capacitors.

By 2010 | “Total technology” and leadership in multilayer polymer (MLP)

• By 2010 — ITW Paktron is described as a multi-product, international company headquartered in Lynchburg, Virginia, with manufacturing in the U.S. and Taiwan.

• By 2010 — Paktron emphasizes a “total technology” approach—developing not only capacitors, but also the equipment and process technology used to manufacture them.

• By 2010 — Paktron is positioned as a technology leader in multilayer polymer film capacitors (MLP), highlighting high ripple-current capability and rare SMT compatibility for film capacitors.

2011–Present | New ownership, platform growth, and next-generation performance
