JUICE Mission to Jupiter: Exxelia components ready to withstand extreme space conditions

On April 14, 2023, the JUICE (JUpiter ICy moons Explorer) mission will launch to explore the icy moons of Jupiter. It is an incredible event that has been long-awaited by astronomy enthusiasts. But did you know that components from Exxelia are on board this satellite?

Mission Juice ESAExxelia is known for the quality and reliability of its products, making it a popular choice for space missions.

Exxelia components are used in many embedded systems on board the JUICE mission, including capacitors (High Voltage C Series X7R & TCK Series X7R, CEC Series NP0, Polyester PET PM 948) and magnetics (Inductors MPCI, CMC, SESI inductors, Common mode choke and specific transformers). They have been carefully designed and tested to withstand the extreme conditions of space.

Exxelia has been working closely on this project for more than 10 years, notably on the GALA (GAnymede Laser Altimeter) and MAJIS (Moon and Jupiter Imaging Spectrometer) instruments.

 

Conditions in space are extreme, with high levels of radiation, drastic temperature variations, and intense vibrations. Exxelia components have been designed to withstand these conditions, providing consistent and reliable performance throughout the mission.

 

1st European mission to Jupiter. Focusing on its icy moons and evaluating the potential for habitable worlds.

The JUICE mission is an ambitious undertaking that aims to explore Jupiter's icy moons and study their composition and history. This mission will help us better understand the evolution of the solar system and search for signs of life beyond Earth.

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 @ 500 VDC. The lowest ESR is obtained by combining highly conductive metal electrodes and proprietary of the NPO low loss rugged dielectrics. NHB series is particularly fit 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 Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia has developed with support of ESA and CNES, a new high-end dielectric material, E7000 series, designed for high-end filters where high Q factor is requested. 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 provides high-performance requested for space use in the frequency range 5 to 32 GHz, and guarantees up to Qxf > 250 000 at 10GHZ. Typical applications: Satellite multiplexing filter devices, radio links for communication systems (LMDS), military radars.

Exxelia adopte le marquage laser pour ses produits

Le marquage Laser s’inscrit dans la démarche GREEN qu'Exxelia met en place depuis peu pour ses produits. En effet, il permet la réduction de la présence de produits chimiques dans les produits magnétiques Exxelia, actuellement, identifiés par marquage encre qui nécessite l’utilisation de vernis de protection afin de résister aux agents chimiques de nettoyage utilisés par nos clients. De plus, il permet une production GREEN avec la réduction drastique des consommables (généralement chimiques) liés au marquage encre et donc du besoin en recyclage, pour moins d’impact sur l’environnement. Exxelia s'inscrit dans une démarche écoresponsable avec notamment de nombreux avantages industriels, à savoir : Marquage indélébile => une traçabilité optimale (même sur les plus petits produits), permanente et de qualité constante. Résistance à la corrosion et à la chaleur. Résistance aux agents chimiques => plus besoin d’utiliser des vernis de protection sur nos marquages. Plus d’utilisation de consommables (comparativement avec un marquage encre).
