Exxelia at Space Tech Expo – Booth #5009

Exxelia is pleased to exhibit at Space Tech Expo 2017 in Pasadena, California. From May 23th to 25th at booth # 5009, Exxelia will be showcasing innovative solutions dedicated to space applications.


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 power and high frequency ceramics with the new C48X dielectric

Range of high voltage ceramic capacitors based on brand new dielectric material C48X, combining most advantages of NPO and X7R dielectrics. Compared to X7R material, C48X dielectric allows to get the same capacitance values under working voltage with the unrivaled advantage of a very low dissipation factor (less than 5.10–4). Besides, it can also withstand very high dV/dt, up to 10kV/μs, which makes it the solution of choice for pulse and fast charge/discharge applications or firing units. Thus capacitors with C48X dielectric appear to be ideally suited for power applications where heat dissipation may be detrimental to performances and reliability.

Magnetic components based on adaptive CCM technology

Exxelia designed CCM technology to respond to the growing interest of electronic engineers for inductors and transformers with multiple outputs, high power density and reduced footprint.

Qualified for aeronautic and space applications, the CCM product line features terrific robustness. The CCM technology adapts to most every need, even the harshest environments, including VIGON® resistance. The series offers five different sizes, allowing optimized component design in a pick-and-place surface mount (SMD) package. Through-hole (TH) packages are also available upon request. CCM transformers and inductors can operate over a wide temperature range with a minimal temperature of -55° C. The standard thermal grade of the technology is 140° C. The epoxy molding protecting the winding ensures a lower temperature gradient and a better heat dissipation. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC.

Euclid : La mission de l'ESA embarque nos composants magnétiques et condensateurs.

Cette réalisation remarquable vient s'ajouter à notre participation réussie à la mission JUICE de l'ESA et à la présence de nos composants à bord du rover Perseverance de la NASA. Euclid est une mission spatiale ambitieuse de l'Agence Spatiale Européenne (ESA) qui vise à cartographier l'Univers observable et à enquêter sur la mystérieuse énergie sombre et la matière noire. Le satellite étudiera des galaxies qui se trouvent à différentes distances de la Terre au moyen d’un télescope de 1,2m de diamètre qui embarque deux instruments : l’imageur observant en lumière visible (VIS) et le spectro-imageur proche infrarouge (NISP). Nous sommes fiers d'avoir été sélectionné comme fournisseur de composants passifs de haute fiabilité pour cette mission cruciale. Nos composants magnétiques (CMC 15, SESI inductance 9.1, 15 & 22) et nos condensateurs (PM 948S, PM 94S, DBIT X3S) ont été soigneusement conçus et fabriqués pour répondre aux exigences extrêmes de l'espace (ESA QPL) et jouer un rôle clé dans le succès de la mission Euclid (Nous équipons le PCDU = Unité de distribution de conditionnement de puissance).  Notre expertise et notre expérience dans la conception et la fabrication de composants électroniques passifs sur mesure pour le domaine spatial, nous permettent de répondre aux exigences les plus strictes de l'industrie aérospatiale. Nous sommes déterminés à maintenir notre position en tant que fournisseur de confiance pour les missions spatiales de renom.   Crédit image : ESA/C. Carreau,CC BY-SA 3.0 IGO View the press release
