Exxelia revolutionary MML™ ultra-high energy density Film Capacitors
Exxelia, a leading manufacturer of ruggedized passive components and sub-systems dedicated to demanding markets, today introduced Miniature Micro-Layer™ (MML™) capacitors, a breakthrough technology that allows tremendous size and weight reduction thanks to an unrivaled energy density.
MML™ is a revolutionary new technology that provides the highest capacitance per volume in film capacitors available on the market.
Why is it a game changer? Because an unparalleled energy density of 400 J/dm3 allows for a tremendous reduction in size and weight compared to traditional Polypropylene or Polyester dielectrics, together with an increased operating temperature up to 140 °C and transient voltage protection.
Besides, MML™ capacitors offer a large flexibility in design, easily allowing low profile configurations.
Several studies have been conducted on actual cases of controls and DC-Links functions for aircraft applications. All have shown about 50% reduction in size and weight compared to other film technologies.
The comparative picture with MLCC is even more flattering, as it demonstrates between 70% to 90% reduction in weight, while showing no capacitance derating with voltage applied and a low drift < 5% through the temperature range. Applications using clusters of stacked MLCCs can now be replaced by a single MML™ unit of similar size, with all the increased reliability that film dielectric offers.
With such outstanding properties, Exxelia new MML™ capacitors are perfectly suitable for 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 applications of confined electronics.
Samples are readily available on request.

Participation in the "Industry of the future" program by GIFAS
"Industry of the Future" Program Launched in 2019, for four years, financed by the government, as well as the Regions, OPCO2i, companies and GIFAS: the "Industry of the Future" program aims to strengthen the competitiveness of the sector through the introduction of new 4.0 technologies. This program, which is the result of close collaboration between the Industrial Committee, the GEAD and the AERO-PME Committee, is a continuation of the "Industrial Performance" program. Its objective is to use new digital and production technologies in all phases of a product's life. In this respect, the Exxelia sites of Illange and Marmoutier are concerned. Frédéric BOIS, in his capacity as Director of the Exxelia site of Illange, was able to actively participate in the exchanges. The objectives were numerous, namely : Inventory of the industrial maturity of our site of Illange. Analysis. Recommendation and deployment of Industry 4.0 tools best suited to the situation of each company. Thanks to the Grand Est region which contributes to the financing of the program, to the partners: Cetim - Technical center of mechanical industries, BoostAeroSpace SAS, UIMM, DREETS, OPCO 2i, and of course to AERIADES as a facilitator of the aeronautical sector in the region.

QPL CERTIFICATION for PM907S & PM948S SERIES OF FILM CAPACITORS
Series PM907S and PM948S of Film capacitors obtained the QPL certification from the European Space Components Coordination (ESCC). According to the ESCC Detail Specification No. 3006/025 and 3006/026 QPL certified products ensure superior performances, quality and reliability intended for use by the European Space Agency (ESA) and in Space in general. PM907S and PM948S are full series of Polyester Film Capacitors. PM907S products are suitable for voltages from 50V up to 1250V and offer capacitance values from 82nF up to 180μF. PM948S can be used with a voltages from 50V up to 630V with capacitance values from 22nF up to 47μF. Both series can support extreme conditions with temperatures from -55°C to +125°C, and offer high energy density, low ESR & ESL and high RMS current. Products are typically being used in SMPS (Switch Mode Power Suppliers) and BUS filtering. These two certified series complete the list of Exxelia Group’s QPL certified film capacitors, that now includes: – PM90S – PM907S – PM96S (T) – PM94S – PM948S – MKT5 – KM111S – KM94S
