Mission JUICE vers Jupiter : Les composants Exxelia prêts à résister aux conditions extrêmes de l'espace

Le 14 avril 2023, la mission JUICE (JUpiter ICy moons Explorer) décollera pour explorer les lunes glacées de Jupiter. C'est un événement incroyable qui est attendu depuis longtemps par les passionnés d'astronomie. Mais saviez-vous que des composants d’Exxelia sont à bord de ce satellite ?

Exxelia est réputée pour la qualité et la fiabilité de ses produits, ce qui en fait un choix populaire pour les missions spatiales.

Les composants Exxelia sont utilisés dans de nombreux systèmes embarqués à bord de la mission JUICE, notamment les condensateurs (High Voltage C Series X7R & TCK Series X7R, CEC Series NP0, Polyester PET PM 948) et les magnétiques (Inductances MPCI, CMC, SESI inductance, Common mode choke et des transformateurs sur mesure). Ils ont été soigneusement conçus et testés pour résister aux conditions extrêmes de l'espace.

Exxelia travaille en étroite collaboration sur ce projet depuis plus de 10 ans, notamment sur les instruments GALA (Altimètre laser)  et MAJIS (Spectromètre Imageur des Lunes et de Jupiter).

 

Les conditions dans l'espace sont extrêmes, avec des niveaux de radiation élevés, des variations de température drastiques et des vibrations intenses. Les composants Exxelia ont été conçus pour résister à ces conditions, offrant une performance constante et fiable pendant toute la durée de la mission.

La mission JUICE est une entreprise ambitieuse qui vise à explorer les lunes de glace de Jupiter et à étudier leur composition et leur histoire. Cette mission permettra de mieux comprendre l'évolution du système solaire et de rechercher des signes de vie en dehors de la Terre.

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'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's Power Distribution Unit (PDU). Exxelia'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.

Exxelia to showcase advanced Microwave Capacitors and Ferrites at IMS Microwave week 2024

Exxelia will be showcasing their Super High-Q series of RF ceramic capacitors. These capacitors feature ultra-low ESR and can operate at voltages up to 1500V. They are available in sizes ranging from 0402 to 1210, offering capacitance values from 0.1pF to 1 000pF. They are ideal for advanced RF applications such as power amplifiers, mixers, filters and matching networks.  Exxelia also features advanced High-Power High-Q series, designed for lower frequency applications with power handling up to 7200V and capacitance value up to 10nF. These capacitors are available in NPO and P90 dielectrics, offering exceptional performance with low ESR and ESL, making them ideal for the most demanding application. Those CP (P90) and CL (NP0) series are ideal for defense communication (VHF/UHF), medical MR body coils, and RF generators for plasma, semiconductor manufacturing, and extreme ultraviolet (EuV) lithography.    Exxelia will also exhibit its comprehensive range of materials & tuning components, with a special focus on its cutting-edge microwave ferrite products. These advanced components are engineered to meet the rigorous demands of modern microwave applications, providing unparalleled performance and reliability.    As a highlight of our presence at IMS Microwave Week, Exxelia will be pre-launching a new High-epsilon microwave ferrite. This new High-Epsilon Ferrite is featuring a permittivity of 21 and is available in two versions (YK21 and DK21) to address all power applications. It represents a significant advancement in ferrite technology, engineered to enhance the performance of high-frequency radar systems, especially in Active Electronically Scanned Array (AESA) radar applications. This new component delivers exceptional magnetic properties and stability, crucial for the optimal performance of isolator and circulator devices.       Key Features and Benefits about the new high-epsilon ferrite YK21 and DK21:  High permittivity : 21 Two power levels available  : ∆Hk = 4.5 and ∆Hk = 8.5 Wide range of Ms : 1250 to 1900 Gauss Frequency applications up to X band (12GHz). Combination with Exxelia dielectric range for Ferrite Dielectric Assembly (FDA) Short leadtime of 8-10 weeks for evaluation.                                        Meet Us at IMS Microwave Week 2024   We invite you to visit us at IMS Microwave Week 2024, from June 16-21 in Washington, D.C., at booth 2108. Our team of experts will be available to discuss the capabilities of the High-Epsilon Ferrite YK21-DK21 and how it can enhance your high-frequency applications.
