Discover the power of MML™ technology

The best performing film capacitors on the market with the highest energy density ever!

Condensateur MML

Exxelia's revolutionary MML™ ultra-high energy density Film Capacitors are a game changer in the industry due to their unparalleled energy density of 400 J/dm3. This allows for a significant reduction in size and weight in comparison to traditional Polypropylene or Polyester dielectrics, as well as an increased operating temperature of up to 140°C and protection against transient voltage.

Not only do MML™ capacitors offer a large flexibility in design, allowing for low profile configurations, but they have also been tested in actual cases for controls and DC-Links functions in aircraft applications and have shown a reduction in size and weight of about 50% compared to other film technologies.

 

Furthermore, when compared to MLCCs, MML™ capacitors have demonstrated a reduction in weight of between 70% to 90%, with no capacitance derating with voltage applied and a low drift of less than 5% across the temperature range. Applications that previously required clusters of stacked MLCCs can now be replaced by a single MML™ unit of similar size, with the added reliability that film dielectric offers.

The exceptional properties of Exxelia's new MML™ capacitors make them suitable for a wide range of applications including power supplies, DC-links, AC/DC/AC power converters, charge/discharge or power generation functions of commercial/military aircraft, satellite platforms and payloads, launchers, defibrillators, downhole tools and any other applications that require confined electronics.

Exxelia joins Heico Corporation group

The transaction will be carried out with IK Partners, majority shareholder of Exxelia since 2015, and should take place before the end of the first quarter of 2023.   Laurans A. Mendelson, HEICO&#39;s Chairman and Chief Executive Officer, along with Victor H. Mendelson, HEICO&#39;s Co-President and CEO of its Electronic Technologies Group, commented, "We are ecstatic that such a fine company, with its remarkable team members, management and products, will be part of HEICO, and we look forward to welcoming all of Exxelia&#39;s great people to the HEICO family. While furthering HEICO&#39;s strategy of expanding our already impressive range of mission-critical and Hi-Rel components for the most demanding applications, Exxelia also provides HEICO with added broad geographic and product diversity, including in the important European market."   Paul Maisonnier, CEO of Exxelia, commented, "We are excited to embark on a new stage of development with HEICO. We really appreciate the values of the Mendelson Family, which match perfectly those of Exxelia. Our goal to develop Exxelia into a world leader in Hi-Rel passive components and sub-systems for harsh environments, serving the aeronautic, defense, space and medical markets will be accelerated under the HEICO umbrella. Together we will strengthen our innovation and operational capabilities and accelerate our internationalisation strategy. We thank IK for their support over the past years, which has enabled us to establish a solid platform to support our ambitions for global growth."   Dan Soudry, Managing Partner at IK Partners and Advisor to the IK VII Fund, and Diki Korniloff, Partner at IK Partners, added: "As shareholders of Exxelia since 2015, we are very pleased to have been able to support its very talented management team through the various stages of transformation, structuring and growth of the Company, doubling its employee base to more than 2,100 people and leading to a strong increase in investment in R&D and in its manufacturing footprint. Notably, we believe that HEICO is an excellent home for Exxelia given that they share common values and we are very pleased HEICO is acquiring Exxelia. We&#39;d like to take this opportunity to wish the team and HEICO all the very best for the future."     About HEICO Corporation HEICO Corporation is engaged primarily in the design, production, servicing and distribution of products and services to certain niche segments of the aviation, defense, space, medical, telecommunications and electronics industries through its Hollywood, Florida-based Flight Support Group and its Miami, Florida-based Electronic Technologies Group.
