Fusion d'Exxelia Microspire et Exxelia N'Ergy

Exxelia annonce la fusion de ses deux sociétés Exxelia Microspire et Exxelia N’Ergy. Les deux entités sont désormais rassemblées sous un même nom : Exxelia Magnetics.


Exxelia Magnetics regroupe toutes les activités de conception, fabrication et industrialisation de composants magnétiques bobinés, du groupe en France : transformateurs et inductances, électroaimants, rotors et stators.

Cette fusion vise à améliorer les services réalisés auprès des clients et autres collaborateurs mais également à simplifier les démarches administratives et commerciales. L’organisation actuelle des entreprises, les sites et leurs fonctions allouées restent inchangés.

Exxelia Microspire conçoit, industrialise et fabrique depuis plus de 35 ans des composants bobinés : transformateurs et inductances, électroaimants, rotors et stators.

Exxelia Microspire dispose de plusieurs sites de fabrication dont notamment des sites à faibles coûts de production nouvellement installés, permettant de proposer des solutions compétitives.

Le savoir-faire d’Exxelia Microspire inclut les technologies standards de bobinage linéaire (formats RM, ETD, EP, EFD, ER, EQ..) et toroïdal. Pour les marchés à environnements sévères (chocs, vibration, hautes températures, …). Exxelia Microspire dispose de technologies spécifiques et innovantes telles que les technologies SESI, TT et CCM.

La qualification de ses technologies, la définition des règles de conception associées et son organisation industrielle lui permettent de proposer à ses clients des solutions optimales.

Exxelia N’Ergy est spécialisée dans la conception, la fabrication de composants électromagnétiques passifs spécifiques, en petite et moyenne série.

Exxelia N’Ergy propose :

  • l’étude et la conception de composants électromagnétiques spécifiques avec conducteurs cuivre ou aluminium destinés aux domaines de la conversion d’énergie de produits embarqués,
  • la fabrication de bobinages linéaires ou toriques en petite et moyenne série en fourniture complète ou partielle,
  • le surmoulage de composants électromagnétiques ou de cartes (potting),
  • le contrôle électrique 50 ou 400 Hz.

Exxelia revolutionary MML™ ultra-high energy density Film Capacitors

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. Features & Benefits : Miniaturization of the function : Up to 50% size reduction vs other film technologies ; matching footprint with stacked MLCC Lightweight : 50% lighter vs other film technologies ; 80 to 90% lighter than ceramic No capacitance derating in voltage, stable in temperature (<5% drift through the temperature range) Capacitance from 1μF to 1000μF  Voltages from 50V to 1000V  Operating Temperature -55 °C to +140 °C Highly customizable

Exxelia equips the Turkish satellite IMECE with tantalum and ceramic capacitors

IMECE is a technological feat that pushes the boundaries of high-resolution imaging. Exxelia is proud to play an essential role in this space adventure by providing quality components to ensure proper operation.   IMECE is an earth observation satellite designed and developed by TÜBİTAK Space Technologies Research Institute (TÜBİTAK UZAY) and produced in Türkiye to provide high-resolution imagery. The spacecraft has a mass of 800 kg (1,800 lb) and it will serve at 680 km (420 mi) on a sun-synchronous geocentric orbit. The Satellite, projected for a mission duration of five years, has 0.99m image resolution of Panchromatic (PAN). The satellite has been launched on 15 April 2023 on a SpaceX&#39;s Falcon 9 Block 5 rocket as part of the Transporter-7 ridershare mission.   Exxelia equips the satellite with PM series capacitors that are used in the satellite&#39;s Power Distribution Unit (PDU). Exxelia&#39;s PM series capacitors are renowned for their reliability, performance, and durability, making them ideal for space applications. Exxelia also supplies tantalum capacitors and ceramic capacitors for the payloads of the IMECE Satellite. These components are designed to withstand the extreme conditions of space and ensure the proper operation of scientific instruments and equipment on board the satellite.   We look forward to the discoveries and data that the IMECE Satellite will provide during its five-year mission. The future of space exploration looks promising, and Exxelia will continue to play an active role in this exciting adventure.
