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.

Ultra low ESR, high RF power and high self-resonant frequency The NHB series is a complete range of MLCC based on NPO dielectric material providing a very high Self Resonant Frequency and limiting the parasite Parallel Resonant Frequencies. The series is available in 1111 size with capacitance ranging from 0. 3pF to 100pF. NHB series offers excellent performance for RF power applications at high temperature up to 175°C and at 500 VDC. The lowest ESR is obtained by combining highly conductive metal electrodes and proprietary of new NPO low loss rugged dielectrics. NHB series particularly fits for high power and high frequency applications such as: cellular base station equipment, broadband wireless service, point to point / multipoint radios and broadcasting equipment. Typical circuit applications: impedance matching, bypass, feedback, tuning, coupling and DC blocking. 100% invar tuning screws with self-locking system   Invar-36 is a unique Iron-Nickel alloy (64 % Fe / 36 % Ni) sought-after for its very low coefficient of thermal expansion. With 1.1 ppm. K–1 between 0°C and 100°C, Invar-36 is about 17 times more stable than Brass which is the most traditional and common alloy Tuning Elements are made of. The working temperature range in Space is so wide that this property becomes essential for a reliable and stable cavity filter tuning. Self-locking system is a technology commonly used on Tuning Element made of Brass or other soft “easy-to-machine” alloys but is innovative and pretty advanced when applied to hard and tough Invar 36. The design consists of two threaded segments separated by two parallel slots. After cutting both parallel slots, the rotor is compressed in its length in order to create a plastic deformation. Thus, an offset is induced between the two threaded segments which generates a constant tensile stress in the rotor from the moment threaded segments are screwed. High Q Factor Dielectric Resonators in large batches Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia with the support of ESA and CNES developed the E7000 series that provides a narrow bandwidth with smaller size. E7000 is Ba-Mg-Ta materials based that combines an ultra-high Q-factor and the possibility to get all the temperature coefficients upon request. E7000 features the high-performance requested for space use in the frequency range from 5 to 32 GHz, and guarantees up to Qxf > 250 000 at 10GHZ. Being one of the few manufacturers producing its own raw materials, Exxelia perfectly masters the production of dielectric resonators. Induced by the success of this new range, the company is now able to provide larger batches (up to 20kg of powder) of its E7000 series while keeping the exact same product properties, resulting in opportunities for cost-effective volume fabrication.
